Additional or substituted Members may be admitted to the Company, only with the approval of the Board of Directors and subject to the other provisions of this Agreement. No Member shall have any right or power to resign from the Company (except that a Member who no longer owns any Shares shall hereby cease to be a Member and a Member shall cease to be a Member upon the occurrence of any of the events specified inSection 18-304 of the Act unless otherwise determined by the Board of Directors), and no Member shall be entitled to receive any distribution from the Company (pursuant toSection 18-604 of the Act or otherwise) upon or by reason of any purported resignation from the Company. Any additional Member admitted to the Company shall agree to be bound by the terms and conditions of this Agreement by executing a counterpart signature page hereto.

2.06Directors as Members. A Director may hold an interest in the Company as a Member, and such individual’s rights and interest as a Director shall be distinct and separate from such individual’s rights and interest as a Member.

2.07Liability of Members. The liability of the Members for the losses, debts and obligations of the Company shall be limited to their capital contributions, if any; provided, however, that under applicable law, the Members may under certain circumstances be liable to the Company to the extent of previous distributions made to them in the event that the Company does not have sufficient assets to discharge its liabilities. Without limiting the foregoing, (i) no Member, in his, her or its capacity as a Member, shall have any liability to restore any negative balance in his, her or its Capital Account, and (ii) the failure of the Company to observe any formalities or requirements relating to exercise of its powers or management of its business or affairs under this Agreement or the Act shall not be grounds for imposing personal liability on the Members for liabilities of the Company.

ARTICLE III

Shares; Capital Contributions; Conversion

3.01Shares. All limited liability company interests in the Company shall be denominated in Shares, which may be Common Shares, Incentive Shares or Preferred Shares. The total number of Shares that the Company shall have authority to issue is 204,717,307 Shares, classified as (i) 51,310,614 shares of Series A Preferred Shares (the “Series A Preferred Shares”), 51,217,321 of which are issued and outstanding as of the Agreement Date, (ii) 948,225 shares of Series A Prime Preferred Shares (the “Series A Prime Preferred Shares”), 948,225 of which are issued and outstanding as of the Agreement Date, (iii) 39,275,790 shares of Series B Preferred Shares (the “Series B Preferred Shares”), 19,158,922 of which are issued and outstanding as of the Agreement Date (after giving effect to the transactions contemplated by the Series B Preferred Shares Purchase Agreement), (iv) 100,000,000 Common Shares (the “Common Shares”), 6,311,246 of which are issued and outstanding as of the Agreement Date, and (v) 13,182,678 Incentive Shares (the “Incentive Shares”), 4,827,991 of which are issued and outstanding as of the Agreement Date.

3.02Capital Accounts. For each Member (and each permitted assignee), the Company shall establish and maintain a separate Capital Account. The Capital Account of each Member as of the Agreement Date is set forth on the Schedule of Members. The Capital Accounts shall be maintained for the sole purpose of allocating items of income, gain, loss and deduction among the Members and shall have no effect on the amount of any distributions to any Members in liquidation or otherwise.

3.03Capital Contributions.

(a) Each Member has, as of the Agreement Date, contributed to the capital of the Company such amounts as set forth in the books and records of the Company.

(b) Except as otherwise provided in thisArticle III or in Subsection 1.1(b) of the Series B Preferred Shares Purchase Agreement, no Member shall be obligated to contribute any additional capital to the Company without the consent of such Member and the approval of the Board of Directors or permitted to contribute any additional capital without the approval of the Board of Directors and without the Company having complied with or obtained a valid waiver of Section 4 of the Investors’ Rights Agreement. No interest shall accrue on any contributions to the capital of the Company, and no Member shall have the right to withdraw or to be repaid any capital contributed by it or to receive any other payment in respect of its interest in the Company, including without limitation, as a result of any purported resignation of such Member from the Company, except as specifically provided in this Agreement.

3.04Contributions of Additional Capital.

(a) With the approval of the Board of Directors and a Member, and subject to the other provisions of this Agreement, including but not limited toSection 3.03(b), such Member may contribute additional capital to the Company for any purpose related to the conduct of the business of the Company. Subject to the other provisions of this Agreement, any such contribution shall be made in an amount determined by the mutual agreement of the Company, with the approval of the Board of Directors, and the contributing Member, against issuance to such Member of the number and class and Series (if applicable) of Shares approved by the Board of Directors.

(b) The books and records of the Company shall be adjusted to reflect any additional contributions to the capital of the Company made pursuant to thisSection 3.04.

3.05Preferred Shares. The Preferred Shares shall have the voting, distribution, liquidation and other rights as set forth in this Agreement. The Preferred Shares shall be convertible into Common Shares in accordance with the terms ofSection 3.07 hereof.

3.06Incentive Shares.

(a) All Incentive Shares shall be issued in one or more series (each, a “Series”) as shall be determined by the Board of Directors. Unless otherwise determined by the Board of Directors, each Incentive Share with a different Floor Amount shall be designated as a separate Series of Incentive Shares. All Series of Incentive Shares shall have the same rights, powers and

duties as all other Series of Incentive Shares, except with respect to the right to receive distributions and related payments from the Company (which shall be determined in accordance with the applicable provisions of this Agreement) and the right to vote on matters under this Agreement. The Incentive Shares shall have the voting, distribution, liquidation and other rights as set forth in this Agreement, subject to and qualified by the rights of the holders of the Common Shares and Preferred Shares set forth in this Agreement.

(b) Except as otherwise set forth in a written agreement between the Company and such Service Provider (which shall be approved by the Board of Directors), all Incentive Shares issued to a Service Provider shall be subject to (i) forfeiture or repurchase, at the lesser of original cost or fair market value, by the Company, as the case may be, in accordance with the applicable vesting schedule and (ii) with respect to vested Incentive Shares, repurchase at fair market value by the Company upon cessation of such Service Provider’s employment or other engagement by the Company or any other Affiliate of the Company for “Cause”. The Board of Directors may require a Service Provider to execute and deliver an agreement containing, among other things, restrictions with respect to such Service Provider’s ownership of Incentive Shares and the Company’s repurchase rights as set forth herein (a “Restricted Share Agreement”) as a condition of becoming a Member or otherwise being issued any Incentive Shares. Any such Restricted Share Agreement may be executed on behalf of the Company by any Officer other than the Officer who is the Member with respect to such agreement. The execution of a Restricted Share Agreement by a Member shall constitute execution of a counterpart signature page to this Agreement (and agreement to be bound by the provisions hereof) by such Member. If a Person acquires Shares in exchange for services, whether or not the Person also makes payment of property or cash for such Shares, the Company shall adjust the Carrying Value of the Company’s assets pursuant to clause (ii) of the definition of Carrying Value, unless the Company determines that such adjustment is not required for such issuance of Shares.

(c) Unless otherwise approved by the Board of Directors, the Company shall require that any Service Provider that receives an Incentive Share or other equity interest subject to forfeiture or repurchase or otherwise in connection with services provided to the Company or any of its Subsidiaries, to the extent permitted under the Code, make a timely and valid election pursuant to Section 83(b) of the Code and promptly provide the Company with a copy of such election.

(d) Upon a share split, reverse share split or other restructuring of the equity of the Company that changes the number of outstanding Common Shares, the Incentive Shares outstanding shall be similarly adjusted such that the ratio of Incentive Shares outstanding to Common Shares outstanding remains the same.

3.07Conversion of Preferred Shares.

The holders of the Preferred Shares shall have conversion rights as follows (the “Conversion Rights”); provided, however, that each holder of Series B Preferred Shares may not exercise its Conversion Rights in advance of the Second Closing (as defined in the Series B Preferred Shares Purchase Agreement) unless approved by the holders of a majority of the Series B Preferred Shares.

(a)Conversion. Each Preferred Share shall be convertible, at the option of and without payment of additional consideration by the holder thereof, at any time after the date of issuance of such Preferred Share, into such number of Common Shares as is determined by dividing the applicable Original Issue Price by the applicable Conversion Price for such Preferred Share (the resulting conversion rate for Preferred Shares into Common Shares is referred to herein as the “Conversion Rate”), determined as hereafter provided, in effect on the date of conversion. The “Conversion Price” as of the Agreement Date for (i) each Series A Preferred Share shall be equal to $1.147, (ii) each Series A Prime Preferred Share shall be equal to $2.0878, and (iii) each Series B Preferred Share shall be equal to $2.0878; provided, however, that each such Conversion Price shall be subject to further adjustment as set forth in subsection 3.07(f).

(b)Exercise of Conversion Privilege. To exercise its conversion privilege, a Preferred Member shall give written notice to the Company at the principal office of the Company that such holder elects to convert such Preferred Shares. Such notice shall also state the name or names (with address or addresses) in which the Common Shares issuable upon such conversion shall be issued; provided that, if any name or names in which such Common Shares are to be issued reflect a transfer of such Preferred Shares, such transfer and issuance shall be subject to the provisions ofArticle IX. The date the Company receives such written notice, together with assignment, if required, shall be the “Conversion Date.” Such conversion shall be deemed to have been effected immediately prior to the close of business on the Conversion Date. Notwithstanding the foregoing, in the event of a notice of redemption of any shares of Preferred Shares pursuant toArticle X, the conversion rights of the shares designated for redemption shall terminate at the close of business on the last full day preceding the date fixed for redemption, unless the Redemption Price (as defined below) is not fully paid on such Redemption Date, in which case the conversion rights for such shares shall continue until such price is paid in full. In the event of a liquidation, dissolution or winding up of the Company or a Change in Control, the conversion rights shall terminate at the close of business on the last full day preceding the date fixed for the payment of any such amounts distributable on such event to the Preferred Members.

(c)Reservation of Shares. The Company shall at all times when the Preferred Shares shall be outstanding, reserve and keep available out of its authorized but unissued Shares, for the purpose of effecting the conversion of the Preferred Shares, such number of its duly authorized Common Shares as shall from time to time be sufficient to effect the conversion of all outstanding Preferred Shares; and if at any time the number of authorized but unissued Common Shares shall not be sufficient to effect the conversion of all then outstanding Preferred Shares, the Company shall take such action as may be necessary to increase its authorized but unissued Common Shares to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite Member approval of any necessary amendment to this Agreement.

(d)Automatic Conversion. Subject toSection 12.04, upon either (i) a Qualified IPO, or (ii) the date and time, or the occurrence of an event, specified by vote or written consent of the holders of a majority of the outstanding Preferred Shares (voting together as a single class), then all Preferred Shares will automatically be converted into Common Shares at the then applicable Conversion Rate (the time of the Qualified IPO or the date and time specified or the time of the event specified in such vote or written consent is referred to herein as the “Automatic Conversion Time”).

(e)Procedural Requirements. All holders of record of Preferred Shares shall be sent written notice of the Automatic Conversion Time and the place designated for automatic conversion of all such Preferred Shares pursuant to thisSection 3. All rights with respect to the Preferred Shares converted pursuant toSection 3.07(d), including the rights, if any, to receive notices and vote (other than as a holder of Common Shares), will terminate at the Automatic Conversion Time, except only the rights of the holders thereof to receive the items provided for in the next sentence of thisSection 3.07(e). As soon as practicable after the Automatic Conversion Time, the Company shall (i) issue and deliver to such holder, or to his, her or its nominees, a notice of issuance of uncertificated shares and (ii) pay cash as provided inSection 3.07(g) in lieu of any fraction of a share of a Common Share otherwise issuable upon such conversion and the payment of any declared but unpaid distributions on the Preferred Shares converted. Such converted Preferred Shares shall be retired and cancelled and may not be reissued as shares of such series, and the Company may thereafter take such appropriate action (without the need for shareholder action) as may be necessary to reduce the authorized number of Preferred Shares accordingly.

(f)Adjustments to Conversion Price for Diluting Issues.

(i)Special Definition. For purposes of thisSection 3.07(f), “Additional Common Shares” shall mean all Common Shares issued (or, pursuant toSection 3.07(f)(iii), deemed to be issued) by the Company after the Agreement Date, other than the following securities (such securities, “Excepted Issuances”):

(1) Common Shares or securities issued or issuable upon conversion of the Preferred Shares;

(2) securities issued by reason of a Share distribution, split,split-up or similar reorganization that is covered by thisSection 3.07(f);

(3) Common Shares, Incentive Shares or Options issued to employees or directors of, or consultants or advisors to, the Company or any of its Subsidiaries pursuant to a plan, agreement or arrangement approved by the Board of Directors, including a majority of the Preferred Directors;

(4) Common Shares, Incentive Shares or Convertible Securities actually issued upon the exercise of Options issued and outstanding as of the date hereof or Common Shares or Incentive Shares actually issued upon the conversion or exchange of Convertible Securities issued and outstanding as of the date hereof, in each case, provided such issuance is pursuant to the terms of such Option or Convertible Security;

(5) Common Shares, Options or Convertible Securities issued to banks, equipment lessors or other financial institutions, or to real property lessors, pursuant to a debt financing, equipment leasing or real property leasing transaction approved by the Board of Directors, including a majority of the Preferred Directors;

(6) Common Shares, Options or Convertible Securities issued to suppliers or third-party service providers in connection with the provision of goods or services pursuant to transactions approved by the Board of Directors, including a majority of the Preferred Directors; or

(7) Common Shares, Options or Convertible Securities issued in connection with sponsored research, collaboration, technology license, development, OEM, marketing or other similar agreements or strategic partnerships approved by the Board of Directors, including a majority of the Preferred Directors.

(ii)No Adjustment of Conversion Price. No adjustment in the Conversion Price of any series of Preferred Shares shall be made in respect of the issuance or deemed issuance of Additional Common Shares unless the consideration per Share (as determined pursuant toSection 3.07(f)(v)) for an Additional Common Share issued or deemed to be issued by the Company is less than the Conversion Price for such series of Preferred Shares in effect on the date of, and immediately prior to, such issue.

(iii)Deemed Issue of Additional Common Shares.

(1) If the Company at any time or from time to time after the Agreement Date shall issue any Options or Convertible Securities (excluding Options or Convertible Securities which are themselves Excepted Issuances) or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of Common Shares or Incentive Shares (as set forth in the instrument relating thereto, assuming the satisfaction of any conditions to exercisability, convertibility or exchangeability but without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Common Shares issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date.

(2) If the terms of any Option or Convertible Security, the issuance of which resulted in an adjustment to the Conversion Price of any series of Preferred Shares pursuant to the terms ofSection 3.07(f)(iv), are revised as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (A) any increase or decrease in the number of Common Shares or Incentive Shares issuable upon the exercise, conversion and/or exchange of any such Option or Convertible Security or (B) any increase or decrease in the consideration payable to the Company upon such exercise, conversion and/or exchange, then, effective upon such increase or decrease becoming effective, the Conversion Price of any series of Preferred Shares computed upon the original issue of such Option or Convertible Security (or upon the occurrence of a record date with respect thereto) shall be readjusted to such Conversion Price of such series of Preferred Shares as would have obtained had such revised terms been in effect upon the original date of issuance of such Option or Convertible Security. Notwithstanding the foregoing, no readjustment pursuant to this clause (2) shall have the effect of increasing such Conversion Price to an amount which exceeds the lower of (i) the Conversion Price of any series of Preferred Shares in effect immediately prior to the original adjustment made as a result of the issuance of such Option or Convertible Security, or (ii) the Conversion Price of the any series of Preferred Shares that would have resulted from any issuances of Additional Common Shares (other than deemed issuances of Additional Common Shares as a result of the issuance of such Option or Convertible Security) between the original adjustment date and such readjustment date.

(3) If the terms of any Option or Convertible Security (excluding Options or Convertible Securities which are themselves Excepted Issuances), the issuance of which did not result in an adjustment to the Conversion Price of any series of Preferred Shares pursuant to the terms ofSection 3.07(f)(iv) (either because the consideration per Additional Common Share (determined pursuant toSection 3.07(f)(v)) subject thereto was equal to or greater than the Conversion Price of any series of Preferred Shares then in effect, or because such Option or Convertible Security was issued before the Agreement Date), are revised after the Agreement Date as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (A) any increase in the number of Common Shares or Incentive Shares issuable upon the exercise, conversion or exchange of any such Option or Convertible Security or (B) any decrease in the consideration payable to the Company upon such exercise, conversion or exchange, then such Option or Convertible Security, as so amended or adjusted, and the Additional Common Shares subject thereto (determined in the manner provided inSection 3.07(f)(iii)(1)) shall be deemed to have been issued effective upon such increase or decrease becoming effective.

(4) Upon the expiration or termination of any unexercised Option or unconverted or unexchanged Convertible Security (or portion thereof) which resulted (either upon its original issuance or upon a revision of its terms) in an adjustment to the Conversion Price of any series of Preferred Shares pursuant to the terms ofSection 3.07(f)(iv), the Conversion Price of such series of Preferred Shares shall be readjusted to such Conversion Price as would have obtained had such Option or Convertible Security (or portion thereof) never been issued.

(5) If the number of Common Shares or Incentive Shares issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the Company upon such exercise, conversion and/or exchange, is calculable at the time such Option or Convertible Security is issued or amended but is subject to adjustment based upon subsequent events, any adjustment to the Conversion Price of any series of Preferred Shares provided for in thisSection 3.07(f)(iii) shall be effected at the time of such issuance or amendment based on such number of Shares or amount of consideration without regard to any provisions for subsequent adjustments (and any subsequent adjustments shall be treated as provided in clauses (2) and (3) of thisSection 3.07(f)(iii)). If the number of Common Shares or Incentive Shares issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the Company upon such exercise, conversion and/or exchange, cannot be calculated at all at the time such Option or Convertible Security is issued or amended, any adjustment to the Conversion Price of any series of Preferred Shares that would result under the terms of thisSection 3.07(f)(iii) at the time of such issuance or amendment shall instead be effected at the time such number of shares and/or amount of consideration is first calculable (even if subject to subsequent adjustments), assuming for purposes of calculating such adjustment to the Conversion Price of such series of Preferred Shares that such issuance or amendment took place at the time such calculation can first be made.

(iv)Adjustments of Conversion Price upon Issuance of Additional Common Shares. In the event that after the Agreement Date the Company shall issue Additional Common Shares (including Additional Common Shares deemed to be issued pursuant toSection 3.07(f)(iii)) without consideration or for a consideration per Share less than the Conversion Price for any series of Preferred Shares in effect on the date of and immediately prior to such issue, then and in such event, the Conversion Price of such series of Preferred Shares shall be reduced, concurrently with such issue, to a price (calculated to the nearestone-hundredth of a cent) determined in accordance with the following formula:

CP₂ = CP₁* (A + B) ÷ (A + C).

For purposes of the foregoing formula, the following definitions shall apply:

(1) “CP₂” shall mean the Conversion Price of such series of Preferred Shares in effect immediately after such issue of Additional Common Shares;

(2) “CP₁” shall mean the Conversion Price of such series of Preferred Shares in effect immediately prior to such issue of Additional Common Shares;

(3) “A” shall mean the number of Common Shares and Incentive Shares outstanding immediately prior to such issue of Additional Common Shares (treating for this purpose as outstanding all Common Shares and Incentive Shares issuable upon exercise of Options outstanding immediately prior to such issue or upon conversion or exchange of Convertible Securities (including the Preferred Shares) outstanding (assuming exercise of any outstanding Options therefor) immediately prior to such issue);

(4) “B” shall mean the number of Common Shares or Incentive Shares that would have been issued if such Additional Shares had been issued at a price per share equal to CP₁ (determined by dividing the aggregate consideration received by the Company in respect of such issue by CP₁); and

(5) “C” shall mean the number of such Additional Common Shares issued in such transaction.

(v)Determination of Consideration. For purposes of thisSection 3.07(f), the consideration received by the Company for the issue (or deemed issue) of any Additional Common Shares shall be computed as follows:

(1)Cash and Property. Such consideration shall:

(A) insofar as it consists of cash, be computed at the aggregate amount of cash received by the Company excluding amounts paid or payable for accrued interest or distributions;

(B) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board of Directors; and

(C) in the event Additional Common Shares are issued (or deemed issued) together with other Shares or securities or other assets of the Company for consideration which covers both, be the proportion of such consideration so received, computed at the fair market value thereof, as determined in good faith by the Board of Directors.

(2)Options and Convertible Securities. The consideration per Share received by the Company for Additional Common Shares deemed to have been issued pursuant toSection 3.07(f)(iii) shall be determined by dividing:

(A) the total amount, if any, received or receivable by the Company as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Company upon the exercise of such options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities; by

(B) the maximum number of Common Shares or Incentive Shares (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities.

(vi)[reserved].

(vii)Adjustments for Subdivisions or Combinations of Preferred Shares. If the Company shall at any time or from time to time after the Agreement Date effect a subdivision of the outstanding Common Shares, the Conversion Price of any series of Preferred Shares in effect immediately before that subdivision shall be proportionately decreased so that the number of Common Shares issuable on conversion of each share of such series of Preferred Shares shall be increased in proportion to such increase in the aggregate number of Common Shares outstanding. If the Company shall at any time or from time to time after the Agreement Date combine the outstanding Common Shares, the Conversion Price of any series of Preferred Shares in effect immediately before the combination shall be proportionately increased so that the number of Common Shares issuable on conversion of each Series A Preferred Share shall be decreased in proportion to such decrease in the aggregate number of Common Shares outstanding. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

(viii)Adjustments for Reclassification, Exchange and Substitution. If the Common Shares issuable upon conversion of any series of Preferred Shares shall be changed into the same or a different number of any other class or classes or Series of Shares, whether by capital reorganization, reclassification or otherwise (other than a subdivision or combination of Shares provided for above), then, in any such event, in lieu of the number of Common Shares which the holders of such series of Preferred Shares would otherwise have been entitled to receive upon conversion of their shares of such series of Preferred Shares, each holder of such series of Preferred Shares shall have the right thereafter to convert such holder’s shares of such series of Preferred Shares into a number of Shares of such other class or classes or Series of Shares which it would have been entitled to receive had it converted its shares of such series of Preferred Shares into Common Shares immediately prior to such reorganization or reclassification or other transaction, all subject to further adjustment as provided herein with respect to such other class or classes or Series of Shares, including appropriate adjustment (as determined in good faith by the Board of Directors) in the application of the provisions in thisSection 3.07(f) with respect to the rights and interests thereafter of the holders of the Preferred Shares, to the extent that the provisions set forth in thisSection 3.07(f) (including provisions with respect to changes in and other adjustments of the Conversion Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any Shares thereafter deliverable upon the conversion of the Preferred Shares.

(ix)Adjustment for Merger or Reorganization, etc. Subject to the provisions ofSection 4.01(b), if there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving the Company in which the Common Shares (but not the Preferred Shares) is converted into or exchanged for securities, cash or other property (other than a transaction covered by thisSection 3.07(f)), then, following any such reorganization, recapitalization, reclassification, consolidation or merger, each share of Preferred Shares shall thereafter be convertible in lieu of the Common Shares into which it was convertible prior to such event into the kind and amount of securities, cash or other property which a holder of the number of Common Shares of the Company issuable upon conversion of one share of Preferred Shares immediately prior to such reorganization, recapitalization, reclassification, consolidation or merger would have been entitled to receive pursuant to such transaction; and, in such case, appropriate adjustment (as determined in good faith by the Board of Directors) shall be made in the application of the provisions in thisSection 3 with respect to the rights and interests thereafter of the holders of the Preferred Shares, to the end that the provisions set forth in thisSection 3 (including provisions with respect to changes in and other adjustments of the Conversion Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities or other property thereafter deliverable upon the conversion of the Preferred Shares.

(x)Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to thisSection 3.07(f), the Company at its expense shall, as promptly as reasonably practicable but in any event not later than ten (10) days thereafter, compute such adjustment or readjustment in accordance with the terms hereof and furnish to each Preferred Member a certificate setting forth such adjustment or readjustment and

showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, upon the written request at any time of any Preferred Member, furnish or cause to be furnished to such holder a like certificate setting forth (i) such adjustments and readjustments, (ii) the Conversion Price at the time in effect and (iii) the number of Common Shares and the amount, if any, of other property which at the time would be received upon the conversion of the Preferred Shares.

(xi)Waiver of Adjustment of Conversion Price. Notwithstanding anything herein to the contrary, any downward adjustment of the Conversion Price of any series of Preferred Shares as a result of the issuance of Additional Common Shares (including Additional Common Shares deemed to be issued pursuant toSection 3.07(f)(iii)) may be waived, either prospectively or retroactively and either generally or in a particular instance, by the consent or vote of the holders of a majority of the outstanding shares of such series of Preferred Shares (each voting as a separate class on anas-converted basis). Any such waiver shall bind all holders of such series of Preferred Shares, including future holders.

(xii)Multiple Closing Dates. In the event the Company shall issue on more than one date Additional Common Shares that are a part of one transaction or a series of related transactions and that would result in an adjustment to the Conversion Price pursuant to the terms of thisSection 3.07(f), and such issuance dates occur within a period of no more than 90 days from the first such issuance to the final such issuance, then, upon the final such issuance, the Conversion Price shall be readjusted to give effect to all such issuances as if they occurred on the date of the first such issuance (and without giving effect to any additional adjustments as a result of any such subsequent issuances within such period).

(xiii) Notwithstanding anything else to the contrary in thisSection 3.07(f),Sections 3.07(f)(ii),(iii),(iv) and(v) shall be null and void and of no further effect with respect to each series of Preferred Shares from and after the date that the Unpaid Preferred Contribution Amount with respect to such series is zero dollars ($0.00).

(g)No Fractional Common Shares. No fractional Common Shares shall be issued upon the conversion of any Preferred Shares and the aggregate number of Common Shares to be issued to a particular holder of Preferred Shares shall be rounded down to the nearest whole share of Common Shares and the Company shall pay in cash the fair market value of any fractional share of Common Shares as of the time when entitlement to receive such fractions is determined. Whether or not fractional Common Shares would be issuable upon such conversion shall be determined on the basis of the total number of Preferred Shares the holder is at the time converting into Common Shares and the number of Common Shares issuable upon such conversion.

3.08No Reissuance of Preferred Shares. No Preferred Shares acquired by the Company by reason of purchase, conversion, redemption or otherwise shall be reissued, and all such Preferred Shares shall be canceled, retired and eliminated from the Preferred Shares which the Company shall be authorized to issue.

3.09Amendment to Schedule of Members. Subject to the other provisions of this Agreement, the Schedule of Members shall be amended from time to time to reflect any change in Share holdings (or other information set forth on the Schedule of Members) pursuant to the terms of this Agreement, and any such amendment may be effected by any Officer, without approval of the Board of Directors or the Members.

ARTICLE IV

Distributions

4.01Distributions.

(a) Except as provided inSections 4.02,4.03 and12.03(b), cash and property of the Company shall only be distributed to the Members, at such times and in such aggregate amounts as the Board of Directors may determine, in the manner set forth in thisArticle IV.

(b) Cash and other property of the Company shall be distributed among the Members in the following order of priority:

(i) First, to the Preferred Members, in proportion to their respective Unpaid Preferred Contribution Amounts, until the Unpaid Preferred Contribution Amount of each such Member has been reduced to zero,

(ii) Second, to the holders of Eligible Shares (regardless of Series), in proportion to their respective number of Eligible Shares (regardless of Series) until the aggregate amount distributed with respect to each Common Share pursuant to thisSection 4.01(b)(ii) equals the Conversion Price of a Series A Preferred Share;

(iii) Third, to holders of Eligible Shares (regardless of Series) and Series A Preferred Shares, in proportion to their respective number of Eligible Shares (regardless of Series) and Series A Conversion Shares until the aggregate amount distributed with respect to each Common Share pursuant toSection 4.01(b)(ii) and thisSection 4.01(b)(iii) equals the Conversion Price of a Series A Prime Preferred Share; and

(iv) Thereafter, to the holders of Eligible Shares (regardless of Series) and Conversion Shares, in proportion to their respective number of Eligible Shares (regardless of Series) and Conversion Shares.

Other then as set forth in the last paragraph of thisSection 4.01(b), any distributions payable with respect to Eligible Shares that are not vested shall be held by the Company and not distributed with respect to such Eligible Shares. If such Eligible Shares are vested at the time of a subsequent distribution, such Eligible Shares shall then be entitled to all prior distributions that have been withheld.

If after the first distribution pursuant to thisSection 4.01(b) there is a subsequent distribution pursuant to thisSection 4.01(b), whether or not the Preferred Shares have been converted into Common Shares, the allocation of the distributions among the Members shall be determined as if such conversion has not occurred.

For the avoidance of doubt, in the event of a Change in Control, any proceeds payable directly to the holders of Shares shall be treated as subject to the distribution provisions of thisSection 4.01(b) and the holders of Preferred Shares and the holders of Eligible Shares shall receive such amounts that they would have been entitled to receive had such proceeds been distributed to the Members as provided in the foregoing provisions of thisSection 4.01(b). Each Member and other holder of Shares, if any, agrees to take such actions as may be required, necessary or advisable to effect the intent of thisSection 4.01(b). In any of such events, if the consideration received by the Company, or payable to the Members, is other than cash, its value shall be deemed to be the fair market value as determined in good faith by the Board of Directors.

4.02Tax Distributions.

(a) On or before March 31, June 30, September 30 and December 31 of each year, the Company shall distribute to each Member an amount in cash equal to the excess, if any, of (A) the product of (i) the Taxable Income of the Member for the previous taxable quarter and (ii) the Tax Rate; over (B) the aggregate amount of distributions previously made to such Member pursuant toSection 4.01(b) during such taxable quarter (excluding any amounts treated as tax distributions for a previous taxable quarter).

(b) Any distributions made pursuant to thisSection 4.02 shall be treated as advances against, and shall reduce the amount of, the next distribution(s) (other than distributions pursuant to thisSection 4.02 for subsequent periods) that the Members otherwise would be entitled to receive pursuant to the terms of this Agreement and shall be applied against any such future distributions until all such advances have been repaid in full.

4.03Withholding and Taxes. Notwithstanding anything to the contrary herein, to the extent that the Board of Directors reasonably determines that the Company is required, or elects, pursuant to applicable law, either (a) to pay tax (including estimated tax) on a Member’s allocable share of the Company’s items of income or gain, whether or not distributed, or (b) to withhold and pay over to the tax authorities any portion of a distribution otherwise distributable to a Member, the Company may pay over such tax or such withheld amount (in each case, a “Withholding Payment”) to the tax authorities, and such amount shall be treated, in the discretion of the Board of Directors, as (i) a distribution to such Member at the time it is paid to the tax authorities (which distributions shall reduce the amount of distributions to which the Member would otherwise be entitled), or (ii) a demand loan to such Member, on such terms as the Board of Directors shall reasonably determine (which terms shall include the payment of interest by the Member on such loan). Repayment of any such demand loan by the Member will not be considered a capital contribution for purposes of this Agreement. Taxes withheld on amounts directly or indirectly payable to the Company and taxes otherwise paid by the Company (other than in the case where the amount of taxes paid by the Company is treated as a demand loan to the Member) shall be treated for purposes of this Agreement as distributed to the appropriate Members and paid by the appropriate Members to the relevant taxing jurisdiction.

4.04Distribution of Assets in Kind.

(a) No Member shall have the right to require any distribution of any assets of the Company in kind. If any assets of the Company are distributed in kind, such assets shall be distributed on the basis of their fair market value as determined by the Board of Directors. Any Member entitled to any interest in such assets shall, unless otherwise determined by the Board of Directors, receive separate assets of the Company and not an interest as atenant-in-common with other Members so entitled in any asset being distributed.

ARTICLE V

Allocation of Net Profits and Net Losses

5.01Basic Allocations.

(a) Except as provided inSection 5.02, which shall be applied prior to thisSection 5.01, Net Profits and Net Losses of the Company for any fiscal period shall be allocated among the Members in such proportions and in such amounts as may be necessary so that following such allocations, the Adjusted Capital Account balance of each Member equals such Member’s then Target Balance.

(b) If the amount of Net Profits or Net Losses allocable to the Members pursuant toSection 5.01(a) for a period is insufficient to allow the Adjusted Capital Account balance of each Member to equal such Member’s Target Balance, such Net Profits or Net Losses shall be allocated among the Members in such a manner as to decrease the differences between the Members’ respective Adjusted Capital Account balances and their respective Target Balances in proportion to such differences.

5.02Regulatory Allocations. Notwithstanding the provisions ofSection 5.01 above, the following allocations of Net Profits, Net Losses and items thereof shall be made in the following order of priority:

(a) Items of income or gain (computed with the adjustments contained in paragraphs (i), (ii), (iii), (vi) and (vii) of the definition of “Net Profits and Net Losses”) for any taxable period shall be allocated to the Members in the manner and to the minimum extent required by the “minimum gain chargeback” provisions of Treasury RegulationSection 1.704-2(f) and Treasury RegulationSection 1.704-2(i)(4).

(b) All “nonrecourse deductions” (as defined in Treasury RegulationSection 1.704-2(b)(1)) of the Company for any taxable period shall be allocated to the Members in proportion to their respective number of Common Shares (determined on anas-converted-to Common-Share basis); provided, however, that nonrecourse deductions attributable to “partner nonrecourse debt” (as defined in Treasury RegulationSection 1.704-2(b)(4)) shall be allocated to the Members in accordance with the provisions of Treasury RegulationSection 1.704-2(i)(1).

(c) Items of income or gain (computed with the adjustments contained in paragraphs (i), (ii), (iii), (vi) and (vii) of the definition of “Net Profits and Net Losses”) for any taxable period shall be allocated to the Members in the manner and to the extent required by the “qualified income offset” provisions of Treasury RegulationSection 1.704-1(b)(2)(ii)(d).

(d) In no event shall Net Losses of the Company be allocated to a Member if such allocation would cause or increase a negative balance in such Member’s Capital Account (determined for purposes of thisSection 5.02(d) only, by increasing the Member’s Capital Account balance by the amount the Member is obligated to restore to the Company pursuant to Treasury RegulationSection 1.704-1(b)(2)(ii)(c) and the amount the Member is deemed obligated to restore to the Company pursuant to Treasury Regulation Sections1.704-2(g)(1) and1.704-2(i)(5)) and decreasing it by the amounts specified in Treasury Regulation Sections1.704-1(b)(2)(ii)(d)(4), (5) and (6).

(e) Except as otherwise provided herein or as required by Code Section 704, for tax purposes, all items of income, gain, loss, deduction or credit shall be allocated to the Members in the same manner as are Net Profits and Net Losses; provided, however, that if the Carrying Value of any property of the Company differs from its adjusted basis for tax purposes, then items of income, gain, loss, deduction or credit related to such property for tax purposes shall be allocated among the Members so as to take account of the variation between the adjusted basis of the property for tax purposes and its Carrying Value in any manner provided for under Code Section 704(c) and the Treasury Regulations issued thereunder as determined by the Board of Directors in its discretion.

(f) The indebtedness of the Company shall be allocated among the Members under Code Section 752 as determined by the Board of Directors in accordance with Code Section 752.

5.03Allocations Upon Transfer or Admission. In the event that a Member acquires an interest in the Company either by Transfer from another Member or by acquisition from the Company, the Net Profits, Net Losses, gross income, nonrecourse deductions and items thereof attributable to the interest so Transferred or acquired shall be allocated among the Members based on a method chosen by the Board of Directors, in its discretion, which method shall comply with Section 706 of the Code and shall be binding on all Members. For purposes of determining the date on which the Transfer or acquisition occurs, the Company may make use of any convention allowable under Section 706(d) of the Code.

5.04Timing of Allocations. Allocations of Net Profits, Net Losses and other items of income, gain, loss and deduction pursuant toSection 5.01 andSection 5.02 shall be made for each fiscal year of the Company as of the end of such fiscal year; provided, however, that if the Carrying Values of the assets of the Company are adjusted pursuant to clause (ii) of the definition of “Carrying Value,” the date of such adjustment shall be considered to be the end of a fiscal year for purposes of computing and allocating such Net Profits, Net Losses and other items of income, gain, loss and deduction.

5.05Capital Accounts Upon Forfeiture of Shares. In the event a Member’s Shares are subject to vesting restrictions, and the Member forfeits all or a portion of such Shares, the Board of Directors shall make such adjustments to allocation of Net Profits, Net Losses and the Capital Accounts of all Members as it may in good faith determine may be necessary to reflect the forfeiture of such Shares, including to comply with the provisions of the Proposed Treasury Regulations pertaining to the treatment of “partnership equity for services” issued on May 24, 2005 or any successor provisions related thereto. To the extent possible, such adjustments shall adjust the Capital Accounts of the Members so that, after such adjustments have been made, the Capital Accounts balances equal the amounts they would have been if the forfeiting Member had the reduced number of Shares, and the other Members’ respective interests in the Company were increased to the extent applicable, as of the date of formation of the Company (or such other date(s) as determined by the Board of Directors to be appropriate to give effect to the terms applicable to a Member on its admission to the Company) and to otherwise properly reflect the economic sharing arrangement associated with the forfeiture of such Shares.

5.06Adjustment Upon Exercise of Compensatory Options. The Board of Directors shall make such adjustments to the Carrying Value of the Company’s assets, allocation of Net Profits and Net Losses and Capital Accounts as it may in good faith determine may be necessary to comply with the provisions of the Proposed Treasury Regulations pertaining to the treatment of “partnership equity for services” issued on May 24, 2005 or any successor provisions relating thereto and to properly reflect the economic sharing arrangement associated with any “compensatory partnership options” as defined in such Proposed Regulation or successor authority.

5.07Adjustment Upon Exercise of Noncompensatory Options. If the Company issues Shares or other securities that are treated as noncompensatory options, as defined in Treasury RegulationSection 1.721-2, the Board of Directors shall make such adjustments to the Carrying Value of the Company’s assets, allocation of Net Profits and Net Losses, Capital Accounts and allocations of items for income tax purposes as it may in good faith determine may be necessary to comply with the provisions of the Treasury Regulations pertaining to the treatment of “noncompensatory options” issued on February 4, 2013 or any successor provisions relating thereto and to properly reflect the economic sharing arrangement associated with the noncompensatory options.

If the Members of a majority of the then-outstanding Series A Preferred Shares, Series B Preferred Shares or Common Shares, as the case may be, fail to elect a sufficient number of Directors to fill all directorships for which they are entitled to elect Directors, voting exclusively and as a separate class, pursuant to the first sentence of thisSection 7.03(a), then any directorship not so filled shall remain vacant until such time as the Members holding a majority of the then-outstanding Series A Preferred Shares, Series B Preferred Shares or Common Shares, as the case may be, elect a person to fill such directorship by vote or written consent in lieu of a meeting; and no such directorship may be filled by Members other than by the Members that are entitled to elect a person to fill such directorship, voting exclusively and as a separate class. At any meeting held for the purpose of electing a Director, the presence in person or by proxy of the Members holding a majority of the outstanding Shares of the Series entitled to elect such Director shall constitute a quorum for the purpose of electing such Director. Except as otherwise provided in thisSection 7.03(a), a vacancy in any directorship filled by the holders of any Series shall be filled only by vote or written consent in lieu of a meeting of the Members of such Series or by any remaining Director or Directors elected by the Members of such Series pursuant to thisSection 7.03(a).

The Board of Directors may appoint from its members a Chairman of the Board and a Vice Chairman of the Board, neither of whom need be an employee of the Company or Officer. If the Board of Directors appoints a Chairman of the Board, such Chairman shall perform such duties and possess such powers as are assigned by the Board of Directors.

7.04Interpretation of Rights and Duties of Members and Directors. To the fullest extent permitted by the Act and other applicable law, and in all instances solely to the extent not inconsistent with the specific provisions of the Certificate and this Agreement, it is the intention and agreement of the parties that:

(a) The Members’ respective obligations to each other are limited to the express obligations set forth in this Agreement, the Investors’ Rights Agreement, the Voting Agreement and the Right of First Refusal andCo-Sale Agreement, subject only to the implied contractual covenant of good faith and fair dealing. No Member shall have any duties or liabilities, including fiduciary duties, to the Company or to any other Member, or to the Board of Directors or any Director, and the provisions of this Agreement, to the extent that they restrict or otherwise modify, or eliminate, the duties and liabilities, including fiduciary duties, of the Members otherwise existing at law or in equity, are agreed by the Members to replace such other duties and liabilities of the Members. Any standard of care or duty imposed by or under the Act or any other law, rule or regulation (or any judicial decision based on or interpreting the same) shall be modified, waived or limited, to the extent permitted by law, as required to permit each Member to act under this Agreement and to make any decision such Member is authorized to make hereunder in such manner as such Member may determine in his, her or its sole and absolute discretion, subject only to the implied contractual covenant of good faith and fair dealing.

(b) The Board of Directors shall act only collectively, substantially in the manner of a Board of Directors of directors of a corporation organized and existing under the DGCL, and no Director acting individually shall, in his or her capacity as a Director, have or exercise any of the rights or powers of the Board of Directors. Each Director, in his or her capacity as such, shall act (or refrain from acting) as such Director determines in good faith is in, or is not opposed to, the best interests of the Company, provided that such action or inaction does not constitute willful misconduct, breach of the implied contractual covenant of good faith and fair dealing or knowing violation of law, and in a manner consistent with a director of a corporation organized under the DGCL and bound by fiduciary duties. For the avoidance of doubt, Directors shall have all such duties and liabilities, including fiduciary duties, to the Company or to any Member, or to the Board of Directors or to any other Director, as such Director would have as a director of a corporation organized under the DGCL. Any standard of care or duty imposed by or under the Act or any other law, rule or regulation (or any judicial decision based on or interpreting the same) shall be modified, waived or limited, to the extent permitted by law, as required to permit each Director and the Board of Directors to act under this Agreement and to make any decision such Director or the Board of Directors (as applicable) is authorized to make hereunder, as long as such action or decision complies with the standard of conduct set forth in thisSection 7.04(b) and is in accordance with the other provisions of this Agreement.

7.05Indemnification and Exculpation.

(a) To the fullest extent permitted by applicable law, the Company is authorized to provide indemnification of (and advancement of expenses to) Directors, Officers and agents of the Company (and any other persons to which the Act or the DGCL permits a limited liability company or corporation to provide indemnification) through this Agreement, agreements with such agents or other persons, vote of Members or disinterested Directors or otherwise, in excess of the indemnification and advancement otherwise permitted by Section 145 of the DGCL.

(b) To the fullest extent permitted by law, a Director shall not be personally liable to the Company or its Members for monetary damages for breach of fiduciary duty as a director. If the Act, the DGCL or any other law of the State of Delaware is amended after approval by the Members of thisSection 7.05(b) to authorize organizational action further eliminating or limiting the personal liability of directors, then the liability of a Director shall be eliminated or limited to the fullest extent permitted by the Act or DGCL as so amended. Any repeal or modification of the foregoing provisions of thisSection 7.05(b) by the Members shall not adversely affect any right or protection of a Director existing at the time of, or increase the liability of any Director with respect to any acts or omissions of such director occurring prior to, such repeal or modification.

7.06Excluded Opportunities. The Company renounces, to the fullest extent permitted by law, any interest or expectancy of the Company in, or in being offered an opportunity to participate in, any Excluded Opportunity. An “Excluded Opportunity” is any matter, transaction or interest that is presented to, or acquired, created or developed by, or which otherwise comes into the possession of, (i) any Director who is not an employee of the Company or any of its Subsidiaries, or (ii) any holder of Series A Preferred Shares or any partner, member, director, shareholder, employee or agent of any such holder, other than someone who is an employee of the Company or any of its subsidiaries (collectively, “Covered Persons”), unless such matter, transaction or interest is presented to, or acquired, created or developed by, or otherwise comes into the possession of, a Covered Person expressly and solely in such Covered Person’s capacity as a director of the Company. Any amendment, repeal or modification of the foregoing provisions of thisSection 7.06 shall not adversely affect any right or protection of any Director, Officer or other agent of the Company existing at the time of such amendment, repeal or modification.

7.07Officers.

(a)Appointment. Subject to and in accordance with the terms of this Agreement, the Board of Directors may appoint officers of the Company with such titles and such responsibilities as the Board of Directors shall from time to time determine (each, an “Officer”).

(b)Qualification. No Officer need be a Director or a Member. Any two or more offices may be held by the same individual.

(c)Tenure. Except as otherwise provided by law, by the Certificate or by this Agreement, each Officer shall hold office until his death, resignation, removal or replacement by the Board of Directors, unless a different term is specified in the action of the Board of Directors appointing him. Any Officer may resign by delivering his written resignation to the Board of Directors. Such resignation shall be effective upon receipt unless it is specified to be effective at some other time or upon the happening of some other event. Any Officer may be removed or replaced at any time, with or without cause, by the Board of Directors. Except as the Board of Directors may otherwise determine, no Officer who resigns or is removed or replaced shall have any right to any compensation as an Officer for any period following his resignation, removal or replacement, or any right to damages on account of such removal or replacement, whether his compensation be by the month or by the year or otherwise, unless such compensation is expressly provided in a duly authorized written agreement with the Company.

(d)Vacancies. The Board of Directors may fill any vacancy occurring in any office for any reason and may, in its discretion, leave unfilled for such period as it may determine any such other office.

(e)Compensation. Officers of the Company shall be entitled to such salaries, compensation or reimbursement as shall be fixed or allowed from time to time by the Board of Directors.

(f)Duties, Rights and Authorization of Officers. Those Officers with titles customarily used in corporations organized under the DGCL, in their respective capacities as such, shall, unless otherwise provided herein or determined by the Board of Directors, have the statutory and customary rights, powers, authority, duties and responsibilities (including fiduciary duties) of officers with similar titles of a corporation organized and existing under the DGCL. The Members and the Board of Directors hereby delegate to each Officer such rights, powers and authority with respect to the management of the business and affairs of the Company as may be necessary or advisable to effect the provisions of thisSection 7.07(f).

7.08Contracts with Members, Directors and Officers. The Company may engage in business with, or enter into one or more agreements, leases, contracts or other arrangements for the furnishing to or by the Company of goods, services, technology or space with, any Member, Director or Officer, or an Affiliate of any Member, Director or Officer, and may pay compensation in connection with such business, goods, services, technology or space, provided in each case the amounts payable thereunder are reasonably comparable to those that would be payable to unaffiliated Persons under similar arrangements, and if the Board of Directors (or, with respect to arrangements in the ordinary course of the Company’s business, an Officer) determines in good faith that such amounts are so comparable, such determination shall be final and binding on the Company and each Member, Director and Officer. Without limiting the foregoing, no contract or transaction between the Company and one or more of the Members, Directors or Officers, or between the Company and any other limited liability company, corporation, partnership, association, or other organization in which one or more of the Members, Directors or Officers are directors or officers (or serve in a similar capacity), or have a financial interest, shall be void or voidable solely for this reason, or solely because the Member, Director or Officer is present at or participates in the meeting of the Board of Directors or a committee of the Board of Directors at which the contract or transaction is authorized or solely because any such Director’s vote is counted for such purpose, if:

(a) The material facts as to the Member’s, Director’s or Officer’s relationship or interest and as to the contract or transaction are disclosed or are known to the Board of Directors or the committee, and the Board of Directors or committee in good faith authorizes the contract or transaction by the affirmative vote of a majority of the disinterested Directors, even though the disinterested Directors be less than a quorum;

(b) The material facts as to the Member’s, Director’s or Officer’s relationship or interest and as to the contract or transaction are disclosed or are known to the disinterested Members entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of disinterested Members holding a majority of the Shares then held by all disinterested Members determined on anas-converted basis; or

(c) The contract or transaction is fair as to the Company (as determined as if the Company were a corporation under DGCL Section 144(a)(3)) as of the time it is authorized, approved or ratified, by the Board of Directors, a committee of the Board of Directors, or the disinterested Members.

Interested Directors may be counted in determining the presence of a quorum at a meeting of the Board of Directors or of a committee that authorizes the contract or transaction.

7.09Successor Indemnification. If the Company or any of its successors or assignees consolidates with or merges into any other Person and is not the continuing, resulting or surviving corporation or entity of such consolidation or merger, then to the extent necessary, proper provision shall be made so that the successors and assignees of the Company assume the obligations of the Company with respect to indemnification of Directors and Officers as in effect immediately before such transaction, whether such obligations are contained in this Agreement, or elsewhere, as the case may be.

ARTICLE VIII

Fiscal Matters

8.01Tax Reports. As soon as reasonably practicable, but in all events within sixty (60) calendar days after the end of each taxable year, the Company shall furnish all Members with SchedulesK-1 and such other information as may be needed to enable the Members to file their federal income tax returns and any required state income tax returns. The Company shall prepare and furnish to the Members such financial and other reports regarding the Company’s activities as the Board of Directors determines to be appropriate. The cost of all such reporting shall be paid by the Company as a Company expense.

8.02Fiscal Year. The fiscal year of the Company shall end on December 31 of each year. The taxable year of the Company shall be the same as its fiscal year except as otherwise required by applicable law.

8.03Partnership Representative.

(a) The Chief Executive Officer shall be the Company’s “partnership representative” within the meaning of Section 6223 of the Code. The partnership representative shall have sole authority to act on behalf of the Company for purposes of subchapter C of Chapter 63 of the Code and any comparable provisions of state or local income tax laws and shall serve as the Company’s partnership representative until his, her or its resignation or until the designation of his, her or its successor, whichever occurs sooner;provided,however, that the partnership representative shall take any action, and refrain from taking any action, as directed by the Board of Directors.

(b) To the extent that, as a result of a determination by a taxing authority or adjudicative body, there is any adjustment for the purposes of any tax law to any items of income gain, loss, deduction or credit of the Company for any taxable period, the Company will use commercially reasonable efforts to cause the financial burden of any “imputed underpayment” (as determined under Section 6225 of the Code) and associated interest, adjustments to tax and penalties (an “Imputed Underpayment”) arising from a partnership-level adjustment that are imposed on the Company to be borne by the Members and former Members to whom such Imputed Underpayment relates as determined by the partnership representative after consulting with the Company’s accountants or other advisers, taking into account any differences in the amount of taxes attributable to each Member because of such Member’s status, nationality or other characteristics. The portion of any Imputed Underpayment attributed to a former Member shall be treated as a Withholding Payment pursuant toSection 4.03 with respect to such former Member. Each Member agrees to indemnify and hold harmless the Company and the partnership representative from and against any and all liability with respect to any Imputed Underpayment required on behalf of, or with respect to, such Member.

(c) The Members agree that, upon the partnership representative’s request, they shall use commercially reasonable efforts to provide it with available information in the Member’s possession regarding their individual tax returns and liabilities that may be necessary under Section 6225(c) of the Code or other state or local rule. Notwithstanding anything else in this Agreement, in no event shall any Member be required to file amended tax returns with respect to any “reviewed year” (within the meaning of Section 6225(d)(1) of the Code) or to cooperate with the alternative procedure to filing amended returns pursuant to Section 6225(c)(2)(B) of the Code or any applicable similar state or local laws.

(d) The obligations of thisSection 8.03, including a Member’s indemnification obligations underSection 8.03(b), shall survive the liquidation and dissolution of the Company and the transfer, assignment or liquidation of a Member’s interest in the Company. If any Member ceases to be a Member, such Member shall keep the Company advised of its contact information until released in writing by the Company from such obligation.

(e) Notwithstanding anything to the contrary in thisSection 8.03, the partnership representative shall not settle any audit, claim or litigation with respect to taxes of or attributable to the operations of the Company to the extent such settlement would result in a disproportionately material adverse impact to any Member without receiving the prior written consent of such Member, which consent shall not be unreasonably withheld, conditioned or delayed; provided that if such settlement has a disproportionately material adverse on a group of Members that hold the same class or series of equity or shares in the Company, a consent of the holders of such class or series holding a majority of such class or series shall consent to such settlement, which consent shall not be unreasonable withheld, conditioned or delayed.

8.04Taxation as Partnership. The Company intends to be treated and taxed as a partnership for United States federal, state and local tax purposes and the Members and the Company will make any necessary elections to achieve this result and refrain from making any elections that would have a contrary result. No Member shall knowingly take (or shall knowingly cause or permit any of its Affiliates to take) any action that is inconsistent with the classification and taxation of the Company as a partnership for United States federal, state and local tax purposes.

8.05Unrelated Business Taxable Income. The Board of Directors shall use reasonable best efforts to conduct the affairs of the Company so that no Member recognizes income that is (i) unrelated business taxable income (as such term is used in Sections 511 through 514 of the Code) or (ii) unrelated debt-financed income within the meaning of Section 514 of the Code solely as a result of its interest in the Company.

8.06United States Trade or Business; Commercial Activities. The Board of Directors shall conduct the affairs of the Company in a manner that will not cause the Company to be treated for United States federal income tax purposes as (i) engaged in a “trade or business within the United States,” within the meaning of Section 864(b) of the Code or (ii) engaged in “commercial activities” within the meaning of Section 892 of the Code.

ARTICLE IX

Transfers of Interests

9.01General Restrictions on Transfer of Interests by Members.

(a) No Member may sell, transfer, assign, pledge, or otherwise dispose of or encumber any of Shares or any right or interest therein, whether voluntarily or by operation of law, or by gift or otherwise (each, a “Transfer”) without the prior written consent of the Company, upon duly authorized action of its Board of Directors. The Company may withhold consent for any legitimate company purpose, as determined by the Board of Directors. Examples of the basis for the Company to withhold its consent include, without limitation, (i) if such Transfer to individuals, companies or any other form of entity identified by the Company as a potential competitor or considered by the Company to be unfriendly; or (ii) if such Transfer increases the risk of the Company having a class of security held of record by 2,000 or more persons, or 500 or more persons who are not accredited investors (as such term is defined in Regulation D promulgated

under the Securities Act), as described in Section 12(g) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and any related regulations, or otherwise requiring the corporation to register any class of securities under the 1934 Act; or (iii) if such Transfer would result in the loss of any federal or state securities law exemption relied upon by the Company in connection with the initial issuance of such Shares or the issuance of any other securities; or (iv) if such Transfer is facilitated in any manner by any public posting, message board, trading portal, internet site, or similar method of communication, including without limitation any trading portal or internet site intended to facilitate secondary transfers of securities; or (v) if such Transfer is to be effected in a brokered transaction; or (vi) if such Transfer represents a Transfer of less than all of the Shares then held by the Member and its Affiliates or is to be made to more than a single transferee; or (vii) if such Transfer would result in the treatment of the Company as an association taxable as a corporation or as a “publicly traded partnership” within the meaning of Code Section 7704.

(b) Except with respect to a Transfer described in Section 9.01(e)(iii) below, if a Member desires to Transfer any Shares, then the Member shall first give written notice thereof to the Company. The notice shall name the proposed transferee and state the number of Shares to be transferred, the proposed consideration, and all other terms and conditions of the proposed Transfer. If the Company consents to such Transfer, the Transferee shall execute and deliver to the Company such documents as the Company deems necessary, appropriate or desirable.

(c) At the option of the Company, the Member shall be obligated to pay to the Company a reasonable transfer fee related to the costs and time of the Company and its legal and other advisors related to any proposed Transfer.

(d) Any Transfer, or purported Transfer, of Shares not made in strict compliance with thisSection 9.01 shall be null and void, shall not be recorded on the books of the Company and shall not be recognized by or on the books of, the Company and any purported transferee in such transaction shall not be or be treated as or deemed to be a Member (or assignee) for any purpose. In the event any Member shall at any time Transfer any Equity Securities (or any interest therein) in contravention of any of the provisions of this Agreement (or any other applicable agreement between the Member and the Company), then each other Member shall, in addition to all rights and remedies at law and equity, be entitled to a decree or order restraining and enjoining such transaction, and the offending Member shall not plead in defense thereto that there would be an adequate remedy at law; it being expressly hereby acknowledged and agreed that damages at law would be an inadequate remedy for a breach or threatened breach of the provisions of this Agreement (and any other applicable agreement between the Member and the Company) concerning such transactions.

(e) Provided that in no event would any such Transfer cause the Company to be treated as a “publicly traded partnership” (as provided in Code Section 7704 and the Treasury Regulations issued thereunder) and the Member otherwise complies with the requirements of this Section 9.01 (including the notice requirement of Section 9.01(b)), the prior written consent of the Company, upon duly authorized action of its Board of Directors shall not be required for (i) the Transfer of Preferred Shares or to the Transfer of any Conversion Shares, (ii) the Transfer of any Shares to or for the benefit of a Member’s spouse, children, parents, uncles, aunts, siblings,

grandchildren and any other relatives approved by the Board of Directors (collectively, “Approved Relatives”) or to a trust established solely for the benefit of such Member and/or Approved Relatives, (iii) the Transfer of Shares as part of the sale of all or substantially all of the Shares by Members (including pursuant to a merger or consolidation), or (iv) any Transfer by a Preferred Member to (A) any of such Preferred Member’s officers, directors, partners, members or other equity owners, or retired partners, retired members or other retired equity owners, or to the estate of any of such Preferred Member’s partners, members or other equity owners or retired partners, retired members or other retired equity owners or (B) any venture capital fund or similar entity that is controlled by or under common control with one or more general partners, managers, or ultimate beneficial owner, or managing members of, or shares the same management company with, such Preferred Member. Notwithstanding the foregoing or anything herein to the contrary, any Transfer by a Member to any Affiliate shall not be subject to the restrictions set forth in this Article IX.

(f) Notwithstanding anything to the contrary in this Agreement, as a condition to any Transfer:

(i) if the transferor of an interest (“Transferor”) who proposes to Transfer such interest (or if such Transferor is a disregarded entity for U.S. federal income tax purposes, the first direct or indirect beneficial owner of such transferor that is not a disregarded entity (the “Transferor’s Owner”)) is a “United States person” as defined in Section 7701(a)(30) of the Code, then such Transferor (or Transferor’s Owner, if applicable) shall complete and provide to both of the transferee and the Company, a duly executed affidavit in the form provided to such Transferor by the Company, certifying, under penalty of perjury, that the Transferor (or Transferor’s Owner, if applicable) is not a foreign person, nonresident alien, foreign corporation, foreign partnership, foreign trust, or foreign estate (as such terms are defined under the Code and applicable United States Treasury Regulations) and the Transferor’s (or Transferor’s Owner’s, if applicable) United States taxpayer identification number, or

(ii) if the Transferor of an interest who proposes to Transfer such interest (or if such Transferor is a disregarded entity for U.S. federal income tax purposes, the Transferor’s Owner) is not a “United States person” as defined in Section 7701(a)(30) of the Code, then such Transferor and transferee shall jointly provide to the Company written proof reasonably satisfactory to the Board of Directors (1) that any applicable withholding tax that may be imposed on such Transfer (including pursuant to Sections 864 and 1446 of the Code) and any related tax returns or forms that are required to be filed, have been, or will be, timely paid and filed, as applicable, or (2) that withholding is not required because the Transferor is not required to recognize any gain or loss by reason of a nonrecognition provision of the Code or other applicable exception and that any required notices or forms have been, or will be, timely filed.

(g) In addition to any other provision in this Agreement, a transferee of a Common Share, or any interest therein, shall become a Member entitled to all the rights of a Member if, and only if the transferee executes and delivers any applicable Restricted Share Agreement and such other instruments, in form and substance satisfactory to the Board of Directors, as may be necessary, appropriate or desirable to effect such substitution and to confirm the agreement of the transferee to be bound by the terms and provisions of this Agreement and the aforementioned agreements, if applicable.

(h) If the Company issues certificates representing any Shares, the certificates representing Common Shares shall bear on their face the following legend so long as the foregoing Transfer restrictions are in effect:

“THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A TRANSFER RESTRICTION, AS PROVIDED IN THE OPERATING AGREEMENT OF THE COMPANY.”

ARTICLE X

Redemption

10.01General. Unless prohibited by the provisions of Delaware law governing distributions to members, shares of Preferred Shares shall be redeemed by the Company at a per share price in cash equal to the Redemption Price. The Company shall pay the Redemption Price in three equal annual installments commencing not more than 60 days after receipt by the Company at any time on or after January 5, 2023, from the holders of a majority of the then-outstanding Preferred Shares (voting together as a single class on anas-converted basis), of written notice requesting redemption of all shares of Preferred Shares (the “Redemption Request”). Upon receipt of a Redemption Request, the Company shall apply all of its assets to any such redemption, and to no other purpose, except to the extent prohibited by the provisions of Delaware law governing distributions to members. The date of each such installment shall be referred to as a “Redemption Date”. On each Redemption Date, the Company shall redeem, on a pro rata basis in accordance with the number of shares of Preferred Shares owned by each holder, that number of outstanding shares of Preferred Shares determined by dividing (i) the total number of shares of Preferred Shares outstanding immediately prior to such Redemption Date by (ii) the number of remaining Redemption Dates (including the Redemption Date to which such calculation applies). If on any Redemption Date Delaware law governing distributions to members prevents the Company from redeeming all shares of Preferred Shares to be redeemed on any applicable Redemption Date, the Company shall ratably redeem the maximum number of Shares that it may redeem consistent with such law and shall redeem the remaining Shares as soon as it may lawfully do so under such law.

10.02Redemption Notice. The Company shall send written notice of the mandatory redemption (the “Redemption Notice”) to each holder of record of Preferred Shares not less than 40 days prior to each Redemption Date. Each Redemption Notice shall state:

(a) the number of shares of Preferred Shares held by the holder that the Company shall redeem on the Redemption Date specified in the Redemption Notice;

(b) the Redemption Date and the Redemption Price;

(c) the date upon which the holder’s right to convert such Shares terminates (as determined in accordance withSection 3.07); and

(d) that the holder is to surrender to the Company, in the manner and at the place designated, his, her or its certificate or certificates, if any, representing the shares of Preferred Shares to be redeemed.

10.03Surrender of Certificates; Payment. On or before the applicable Redemption Date, each holder of shares of Preferred Shares to be redeemed on such Redemption Date, unless such holder has exercised his, her or its right to convert such shares as provided inSection 3.07, shall surrender any certificate or certificates (if such shares are then in certificated form) representing such shares (or, if such holder alleges that such a certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of such certificate) to the Company, in the manner and at the place designated in the Redemption Notice, and thereupon the Redemption Price for such shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof. In the event less than all of the shares of Preferred Shares represented by a certificate are redeemed, a new certificate, if such Shares are in certificated form, representing the unredeemed shares of Preferred Shares shall promptly be issued to such holder.

10.04Rights Subsequent to Redemption. If the Redemption Notice shall have been duly given, and if on the applicable Redemption Date the Redemption Price payable upon redemption of the shares of Preferred Shares to be redeemed on such Redemption Date is paid or tendered for payment or deposited with an independent payment agent so as to be available therefor in a timely manner, then notwithstanding that the certificates evidencing any of the shares of Preferred Shares, if such Shares are in certificated form, so called for redemption shall not have been surrendered, dividends with respect to such shares of Preferred Shares shall cease to accrue after such Redemption Date and all rights with respect to such shares shall forthwith after the Redemption Date terminate, except only the right of the holders to receive the Redemption Price without interest upon surrender of their certificate or certificates therefor, if such Shares are in certificated form.

ARTICLE XI

Special Mandatory Conversion

11.01Trigger Event. In the event that any Member who is party to the Series B Preferred Shares Purchase Agreement does not purchase, at or prior to the Second Closing (as defined in the Series B Preferred Shares Purchase Agreement), the number of shares of Series B Preferred Shares that such Member is required to purchase at the Second Closing pursuant to the Series B Preferred Shares Purchase Agreement, then each ten Preferred Shares held by such Member shall automatically, and without any further action on the part of such Member, be converted into one Common Share, effective upon, subject to, and concurrently with, the Second Closing. Such conversion is referred to as a “Special Mandatory Conversion.” Notwithstanding anything in this Agreement to the contrary, in the event that Roche does not purchase its Second Closing Shares at the Second Closing as a result of a CFIUS Filing Requirement (as defined in the Series B Preferred Shares Purchase Agreement), Roche shall not be subject to a Special Mandatory Conversion until such time as the CFIUS Satisfied Condition is met and Roche thereafter fails to purchase its Second Closing Shares at the Subsequent Second Closing (as defined in the Series B Preferred Shares Purchase Agreement) within 10 business days of the fulfillment of the CFIUS Satisfied Condition.

11.02Procedural Requirements. Upon a Special Mandatory Conversion, each such Member holding shares of Preferred Shares converted pursuant toSection 11.01 shall be sent written notice of such Special Mandatory Conversion and the place designated for mandatory conversion of all such shares of Preferred Shares pursuant to thisArticle XI. Upon receipt of such notice, each holder of such shares of Preferred Shares in certificated form shall surrender his, her or its certificate or certificates for all such shares (or, if such holder alleges that any such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Company to indemnify the Corporation against any claim that may be made against the Company on account of the alleged loss, theft or destruction of such certificate) to the Company at the place designated in such notice. If so required by the Company, any certificates surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form satisfactory to the Company, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. All rights with respect to the Preferred Shares converted pursuant toSection 11.01, including the rights, if any, to receive notices and vote (other than as a holder of Common Shares), will terminate at the time of the Special Mandatory Conversion (notwithstanding the failure of the holder or holders thereof to surrender any certificates for such shares at or prior to such time), except only the rights of the holders thereof, upon surrender of any certificate or certificates of such holders therefor (or lost certificate affidavit and agreement), to receive the items provided for in the next sentence of thisSection 11.02. As soon as practicable after the Special Mandatory Conversion and, if applicable, the surrender of any certificate or certificates (or lost certificate affidavit and agreement) for Preferred Shares so converted, the Company shall (a) issue and deliver to such holder, or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Shares issuable on such conversion in accordance with the provisions hereof and (b) pay cash as provided inSection 3.07(g) in lieu of any fraction of a share of Common Shares otherwise issuable upon such conversion and the payment of any declared but unpaid dividends on the shares of Preferred Shares converted and (c) a new certificate for the number of shares, if any, of Preferred Shares represented by such surrendered certificate and not converted pursuant toSubsection 11.01. Such converted Preferred Shares shall be retired and cancelled and may not be reissued as shares of such series, and the Company may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Preferred Shares accordingly.

ARTICLE XII

Dissolution; Liquidation; Conversion

12.01Events Causing Dissolution. The Company shall be dissolved and its affairs wound up upon:

(a) Subject toSection 6.03, Board of Directors approval of the dissolution of the Company;

(b) The time at which there are no Members, unless the Company is continued in accordance with the Act; or

The Company shall not be dissolved upon the death, insanity, retirement, resignation, expulsion, bankruptcy, dissolution or occurrence of any other event which terminates the membership of a Member.

12.02Procedures on Dissolution. Dissolution of the Company shall be effective on the day on which occurs the event giving rise to the dissolution, but the Company shall not terminate until the Certificate shall have been cancelled and the assets of the Company shall have been distributed as provided herein. The Board of Directors or, if no Directors are then serving, a liquidator appointed with the consent of the Members holding a majority of the outstanding Shares then held by all Members (determined on anas-converted basis in accordance withSection 6.02 with the Common Shares and Preferred Shares treated as a single class), shall liquidate the assets of the Company, apply and distribute the proceeds thereof as contemplated by this Agreement and cause the cancellation of the Certificate.

12.03Distributions Upon Liquidation.

(a) After payment of liabilities owing to creditors, the Board of Directors or such liquidator shall set up such reserves as may be required by the Act or other applicable law or as the Board of Directors or such liquidator otherwise deems reasonably necessary for any contingent or unforeseen liabilities or obligations of the Company. Said reserves may be paid over by the Board of Directors or such liquidator to a bank, to be held in escrow for the purpose of paying any such contingent or unforeseen liabilities or obligations and, at the expiration of such period as may be required by the Act or other applicable law or as the Board of Directors or such liquidator may otherwise deem advisable, such reserves shall be distributed to the Members or their assigns in the manner set forth in paragraph (b) below.

(b) After paying such liabilities and providing for such reserves, the Board of Directors or liquidator shall cause the remaining net assets of the Company to be distributed to and among the Members in accordance withSection 4.01(b). In the event that any part of such net assets consists of notes or accounts receivable or other noncash assets, the Board of Directors or liquidator may take whatever steps it deems appropriate to convert such assets into cash or into any other form which would facilitate the distribution thereof. If any assets of the Company are to be distributed in kind, such assets shall be distributed on the basis of their fair market value net of any liabilities.

12.04Conversion to a Corporation.

(a) Notwithstanding anything to the contrary set forth in this Agreement, and without any need for consent or approval of any Member (other than as provided inSection 6.03), the Board of Directors may, at any time upon not fewer than ten (10) days’ prior written notice given to each Member, cause the Company to convert into a corporation (the “Corporation”), by such means, subject toSection 12.04(b) below (including filing of appropriate certificates of conversion and incorporation; merger or consolidation or other business combination; Transfer of all or a part of the Company’s assets; and/or exchange of Shares and other Equity Securities for the securities of such corporation) as the Board of Directors may reasonably select (an “Incorporation”). The Board of Directors shall provide that upon such conversion, each Share of each class and Series and other Equity Securities shall be exchanged for, or otherwise converted into, a security of such corporation (i) having voting rights and powers and economic interest (including liquidation and dividend preferences and similar rights, but excluding any rights to distributions underSection 4.02 or otherwise specific to ownership of an interest in an entity treated as a partnership for federal income tax purposes) substantially equivalent, to the extent determined by the Board of Directors in good faith to be reasonably practicable, to the voting rights and powers and economic interest (including liquidation and dividend preferences and similar rights, but excluding any rights to distributions underSection 4.02 or otherwise specific to ownership of an interest in an entity treated as a partnership for federal income tax purposes) of the Shares of such class and Series and other Equity Securities being so exchanged or otherwise converted; provided, however, the Incentive Shares with a Floor Amount greater than zero may be converted into the same class of Equity Securities as the Common Shares, with such number of Equity Securities adjusted downward to reflect the differences, if any, in the fair market value of the relevant Incentive Share as compared to the fair market value of a share of Common Share and (ii) having such terms, conditions, obligations and liabilities set forth in this Agreement and such other terms, conditions, obligations and liabilities (including mandatory and optional conversion provisions) as are, contained in the Investors’ Rights Agreement, the Voting Agreement, Right of First Refusal andCo-Sale Agreement. In determining the fair market value of Common Shares for purposes of the preceding sentence, such values shall be determined based upon the amount each such Share would receive if the Company sold its assets for their fair market value as a going concern, paid its liabilities and distributed the proceeds in accordance withSection 4.01(b). For the avoidance of doubt, it is the intention of the parties that any shares or the number of shares in the Corporation to be received pursuant to thisSection 12.04 will afford to the party receiving the same economic interest, rights, benefits and obligations as were associated with the held by such party immediately prior to such reorganization, both generally and relative to the holders of other shares of the Corporation (but subject to the terms hereof, including the proviso in the second sentence of this Section 12.04). In addition, the consent to any conversion transaction pursuant to the terms of thisSection 12.04 shall be conclusive and binding on all Members, and the Members hereby waive any dissenters’ or appraisal rights that they may have pursuant to the Act, and agree to take any actions necessary (including voting Shares) in order to facilitate and effect such conversion transaction. The Company and the Members agree to use commercially reasonable efforts to effect such Corporate Conversion in a manner intended to betax-free for the holders of the Units to the extent permitted by any applicable law.

(b) By becoming parties to this Agreement, all Members consent to the conversion of their Shares and other Equity Securities into securities in such corporation in accordance with the terms set forth herein. Consequently, subject to the requirements described inSection 12.04(a), each Member agrees to reasonably cooperate, and cause its Affiliates to reasonably cooperate, to take such actions and execute such documents as the Board of Directors may reasonably request, in order to consummate any proposed conversion or reorganization into a corporation.

(a) Except as set forth inSection 6.03 or otherwise in this Agreement, this Agreement may be modified, supplemented, amended or terminated and the observance of any term hereof may be waived (either generally or in a particular instance and either retroactively or prospectively) only by a written instrument executed by and delivered by the affirmative vote of (i) the Board of Directors and (ii) the holders of a majority of the then-outstanding shares of Preferred Shares (voting together as a single class on anas-converted basis);provided:

(i) this Agreement may not be modified, supplemented, amended or terminated and the observance of any term hereunder may not be waived in a manner that would adversely affect the Preferred Members without the written consent of the Preferred Members holding a majority of the outstanding Preferred Shares held by all Preferred Members;

(ii) this Agreement may not be modified, supplemented, amended or terminated and the observance of any term hereunder may not be waived in a manner that would disproportionately and adversely affect the holders of (A) Series A Preferred Shares without the written consent of the holders of a majority of the then-outstanding Series A Preferred Shares, (B) Series A Prime Preferred Shares without the written consent of the holders of a majority of the then-outstanding Series A Prime Preferred Shares or (C) Series B Preferred Shares without the written consent of the holders of a majority of the then-outstanding Series B Preferred Shares; provided, however, that the creation and/or issuance of a new class or series of senior preferred interest in the Company and correlative amendments to this Agreement shall not, in and of itself, be considered disproportionately adverse to the holders of Series A Preferred Shares, Series A Prime Preferred Shares or Series B Preferred Shares;

(iii) the provisions of Delaware Code Title 8, Section 242(b)(2) shall apply to the Preferred Members,mutatis mutandis, as if the Company were a Delaware corporation rather than a limited liability company;

(v) this Agreement may not be modified, supplemented, amended or terminated and the observance of any term hereunder may not be waived with respect to any Preferred Member, Common Member or Incentive Member without the written consent of such Preferred Member, Common Member or Incentive Member unless such modification, supplementation, amendment or termination or waiver applies to all Preferred Members, Common Members and Incentive Members who own the same Series of Preferred Shares, Common Shares or Incentive Shares, respectively, in the same fashion; and

(vi) subject toSection 6.03, the Board of Directors may amend and modify the provisions of this Agreement and the Schedules or other exhibits hereto to the extent necessary to reflect the issuance of authorized Shares or the repurchase of any Shares, the admission, substitution or removal of any Member and the election, designation, removal, vacancy or resignation of any Director or Officer, in each case to the extent permitted under this Agreement. Any amendment, modification, supplement or waiver so effected shall by binding upon the parties hereto.

(b) Notwithstanding anything herein to the contrary, the Board of Directors may cause the Company to amend or modifyArticle V of this Agreement and related defined terms if the Board of Directors is advised at any time by its legal counsel that the allocations of Net Profits and Net Losses and/or similar items provided for inArticle V are unlikely to be respected for federal income tax purposes, either because of the promulgation and adoption of Treasury Regulations under Code Section 704 or other developments in applicable law. In making any such amendment or modification, the Board of Directors shall cause the Company to use its reasonable best efforts to effect as little change in the tax arrangements among the Members as the Board of Directors shall determine in its discretion to be necessary to provide for allocations of Net Profits and Net Losses and similar items to the Members which it believes will be respected for federal income tax purposes. No such amendment or modification shall give rise to any claim or cause of action by any Member.

(c) Notwithstanding anything herein to the contrary, the Board of Directors may cause the Company to amend this Agreement to add a provision that will allow the Company to qualify under any Treasury Regulation, revenue procedure or other administrative pronouncement promulgated by the United States Treasury Department (including the Internal Revenue Service) (the “Liquidation Value Procedure”) similar to that contained in Internal Revenue Service Notice2005-43,2005-24 I.R.B. 1, pursuant to which the Company may elect to determine the value of equity interests in the Company delivered to any Person in connection with services provided by such Person to the Company by reference to the amount the Person would receive if the Company sold all of its assets at their fair market values and liquidated. Such provision may (i) authorize and direct the Company to file any elections required by the Liquidation Value Procedure and (ii) require all Members to comply with the requirements of the Liquidation Value Procedure and will contain such other provisions as the Board of Directors may determine, after consultation with the Company’s tax advisors, may be necessary to comply with the Liquidation Value Procedure. No such amendment or modification shall give rise to any claim or cause of action by any Member.

(d) Notwithstanding anything herein to the contrary, if any rule or regulation is enacted or promulgated (or if the Board of Directors determines that such enactment or promulgation is imminent), or the Internal Revenue Service issues any notice or announcement or other guidance, regarding or relating to Title XI of the Bipartisan Budget Act of 2015, the Board of Directors may cause the Company to amend this Agreement in any manner as the Board of Directors shall determine in good faith after consultation with tax advisors necessary or advisable. No such amendment or modification shall give rise to any claim or cause of action by any Member.

(e) Notwithstanding anything herein to the contrary,Section 7.05 and thisSection 13.08 may not be modified, supplemented, amended or terminated and the observance of any term of such section may not be waived with respect to any Director without the written consent of such Director, unless such amendment, termination, or waiver applies to all Directors in the same fashion.

13.09Third Party Beneficiaries. Notwithstanding anything to the contrary herein, the provisions of this Agreement are not intended to be for the benefit of any creditor (other than a Member or a Director who, in such capacity, is a creditor) or other Person (other than a Member or a Director in his, her or its capacity as a Member or a Director) to whom any debts, liabilities or obligations are owed by (or who otherwise has any claim against) the Company or any of the Members. Moreover, notwithstanding anything herein to the contrary (but subject to the following sentence), no such creditor or other Person shall obtain any rights under this Agreement or shall, by reason of this Agreement, make any claim in respect of any debt, liability or obligation (or otherwise) against the Company or any Member or Director. Each Indemnitee shall be an express third-party beneficiary of this Agreement with respect to his or her rights as an Indemnitee.

13.10Entire Agreement. This Agreement, the Investors’ Rights Agreement, the Voting Agreement, the Right of First Refusal andCo-Sale Agreement and any and all Restricted Share Agreements (collectively, the “Governance Documents”) embody the entire agreement and understanding among the parties hereto with respect to the subject matter hereof and thereof and

supersede all prior agreements and understandings relating to such subject matter, and the Governance Documents, taken together, shall constitute the limited liability company agreement of the Company for purposes of the Act. The Prior Agreement shall be amended and restated in its entirety as set forth in this Agreement and shall be of no further force or effect. The Members hereby agree that each Member and Director shall be entitled to rely on the provisions of this Agreement, and no Member or Director shall be liable to the Company or any other Member or Director for any action or refusal to act taken in good faith reliance on the terms of this Agreement.

13.11Waiver of Partition. Each Member agrees that irreparable damage would be done to the Company if any Member brought an action in court to dissolve the Company. Accordingly, each Member agrees that he, she or it shall not, either directly or indirectly, take any action to require partition or appraisal of the Company or of any of the assets or properties of the Company, and notwithstanding anything herein to the contrary, each Member (and his, her or its successors and permitted assigns) accepts the provisions of this Agreement as his, her or its sole entitlement on termination, dissolution and/or liquidation of the Company and hereby irrevocably waives any and all right to maintain any action for partition or to compel any sale or other liquidation with respect to his, her or its interest, in or with respect to, any assets or properties of the Company.

13.12Counsel to the Company. Counsel to the Company may also be counsel to a Member with respect to matters related to or unrelated to the Company. The Company has selected Wilmer Cutler Pickering Hale and Dorr LLP (“Company Counsel”) as corporate transaction counsel to the Company. Each Member acknowledges that Company Counsel does not represent any Member in its capacity as a Member in the absence of a clear and explicit written agreement to such effect between the Member and Company Counsel (and then only to the extent specifically set forth in such agreement), and that in the absence of any such agreement, Company Counsel shall owe no duties directly to a Member.
