ARTICLE V

Units; Membership

5.1 Units Generally; Preference Units; Transaction Bonus Plan. (a) (i) The Membership Interests in the Company shall be represented by issued and outstanding Units, which may be divided into one or more types, classes or series, with each type or class or series having the rights and privileges, including voting rights, if any, set forth in this Agreement. As of the date hereof, the authorized capital of the Company shall consist of Common Units, Series A Preferred Units and Series B Preferred Units; provided, however the Board may from time to time create such additional classes or series of Membership Interests, to be designated as Common Units, preferred Units, or such other type of class or series of Membership Interests as the Board shall determine, as provided for herein (and subject to any consents required herein). The holders of record of the Membership Interests shall have such rights and obligations associated with such Membership Interests as are provided herein and in the Designation, should any be adopted, of any such class or series of Membership Interest authorized pursuant to this Agreement. The Company shall maintain an accurate record of the Units and Percentage Interests of all Members on the Members Schedule.

(ii) Effective as of the date of this Agreement, in exchange for, among other things, the elimination of the preference amount payable to the holders of the Series A Preferred Units pursuant to Section 7.2(a)(iii) of the Prior Agreement, each holder of record of Series A Preferred Units outstanding on the date hereof shall be issued a number of Common Units (rounded to the nearest whole Unit) equal to a fraction (x) the numerator of which shall equal the aggregate Original Series A Issue Price for such Series A Preferred Units held of record by such holder, and (y) the denominator of which shall equal 1.17. Effective as of the date of this Agreement, in exchange for, among other things, the elimination of the preference amount payable to the Common Investors pursuant to Section 7.2(a)(ii) of the Prior Agreement, each Common Investor shall be issued a number of Common Units (rounded to the nearest whole Unit) equal to a fraction (x) the numerator of which shall equal the Common Preference Amount for such Common Investor, and (y) the denominator of which shall equal 1.17. The Series A Preference Units and the Common Preference Units for each applicable Member is set forth on Schedule C hereto.

(iii) Any Common Units issued hereunder may, at the Board’s discretion, and subject to any consent required hereunder, be issued as equity incentive intended to constitute “profits interests” (as such term is used for purposes of the Code) and the rules and regulations promulgated thereunder, including Rev. Proc. 93-27 and Rev. Proc. 2001-43. All such profits interests shall entitle its record owner to share in the appreciation in the fair market value of Company property from the date of issuance and not in any fair market value of Company property accrued prior to the issuance of such Units. Immediately prior to the issuance of each such Unit, the Capital Accounts of the Members shall be adjusted and all Company property shall be revalued pursuant to the definition of Book Value. No such Units shall be entitled to any retroactive allocation of the Company’s income, gains, losses, deductions, credits, or other items. To the extent consistent with Section 706(d) of the Code and the Treasury Regulations promulgated thereunder, the Company’s books may be closed at the time any Member is issued such profits interests (as though the Company’s tax year had ended) or the Company may credit to the Member being issued such Units his or its pro rata allocations of the Company’s income, gains, losses, deductions, credits and items for that portion of the Company’s fiscal year after the effective date of the issuance of such Units.

(b) The Membership Interests shall be represented by the Units which shall, unless otherwise provided therein, not be evidenced by any certificate or other written instrument, but shall only be evidenced by this Agreement and the holders of record of the Units shall be as is reflected on the books of the Company. Notwithstanding the foregoing, at the request of any Member, such Member shall be entitled to have its Units certificated in a form established by the Company.

(c) The total number of Units of all classes and series of Membership Interests which the Company shall have the authority to issue shall be: (i) 500,000,000 Common Units; (ii) 71,050,860 Series A Preferred Units; and (iii) 101,812,060 Series B Preferred Units; provided that in no event shall more than such number of Series A Preferred Units be issued absent the Required Series A Consent and in no event shall more than such number of Series B Preferred Units be issued absent the Required Series B Consent.

(d) After the initial closing under the Series B Purchase Agreement, the Company, on such terms and conditions as shall be approved by the Board, may adopt a Transaction Bonus Plan. Subject to the foregoing approval, the Transaction Bonus Plan may be structured as the grant of additional Units of a new class or series of Membership Interest that is only entitled to its proportionate share of the amounts payable pursuant to such plan as a special allocation of Profit hereunder, with such limitations and restrictions thereon as the Board or the Compensation Committee shall deem reasonable or appropriate. The creation of any such new class or series of Membership Interests shall be a Designation pursuant to Section 5.2. The Required Series A Consent and Required Series B Consent shall not apply to a Transaction Bonus Plan, so long as approved by the Board, including the Merck Manager or the Third Investor Manager.

(e) In no event shall any employee, officer or director of the Company, or any other Person, be entitled to any anti-dilution adjustment (or similar right), of any sort, in connection with the issuance of any securities of the Company, other than (i) as specifically provided herein for the benefit of the holders of Preferred Units, (ii) anti-dilution rights granted to employees of the Company and set forth in the Disclosure Schedule to the Series B Purchase Agreement (provided that, after giving effect to the final closing under the Series B Purchase Agreement, no such employee shall be entitled to any further adjustment, and such rights shall no longer be in effect), and (iii) anti-dilution rights hereafter granted to Persons with the approval of the Board (including the approval of each of the Investor Managers, other than with respect to any anti-dilution rights that are consistent with those herein set forth granted to investors in connection with a Qualified Future Financing), including, without limitation, in connection with a Qualified Future Financing.

5.2 Designation of Additional Units.

(iv) whether such class or series shall be subject to redemption by the Company (subject to any required approvals hereunder), and, if made subject to redemption, the times and other terms and conditions of such redemption (including the mandatory or optional nature of such redemption, whether such redemption shall be in whole and/or in part, and the amount and kind of consideration to be received upon such redemption);

(v) the amount or amounts which shall be paid out of the assets of the Company in respect of such class or series upon voluntary or involuntary liquidation, dissolution or winding-up of the Company, and any rights in addition to those set forth in this Agreement in respect of such class or series upon the liquidation, dissolution or winding-up of the Company;

(vii) any limitations and restrictions in addition to those set forth in this Agreement, to be effective while any Units of such class or series are outstanding, upon the allocation of Profits or Losses, or upon the distribution of property with respect to, and upon the purchase, redemption or other acquisition by the Company of, any of the other classes or series of Membership Interests;

(viii) any conditions or restrictions in addition to those set forth in this Agreement upon the issuance of any additional Membership Interests of any class or series;

(c) Subject to any consent required hereunder, any action or actions taken by the Board pursuant to the provisions of this Section shall be deemed an amendment and supplement to, and shall become a part of, this Agreement.

5.3 Issuance of Units. Subject to the limitations contained in this Agreement, including Sections 4.9, 4.10 and 5.5, the Company shall have the right from time to time to issue additional Units to such persons on such terms and for such consideration as the Board shall determine in its discretion.

The Board shall also adjust the Capital Accounts of the Members as necessary in accordance with Section 6.2.

5.5 Preemptive Rights.

(a) Subject to the terms and conditions of this Section 5.5 and applicable securities laws, and any consent required hereunder, if the Company proposes to offer or sell any New Securities, the Company shall first offer such New Securities to each Major Holder.

(b) The Company shall give notice (the “Offer Notice”) to each Major Holder, stating (i) its bona fide intention to offer such New Securities, (ii) the number of such New Securities to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such New Securities.

(c) By notification to the Company within twenty (20) days after the Offer Notice is given, each Major Holder may elect to purchase or otherwise acquire, at the price and on the terms specified in the Offer Notice, up to that portion of such New Securities which equals the proportion that the Common Units issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Preferred Units and any other Derivative Securities then held, by such Major Holder bears to the total Common Units of the Company then outstanding (assuming full conversion and/or exercise, as applicable, of all Preferred Units and other Derivative Securities). At the expiration of such twenty (20) day period, the Company shall promptly notify each Major Holder that elects to purchase or acquire all the securities available to it (each, a “Fully Exercising Major Holder”) of any other Major Holder’s failure to do likewise. During the ten (10) day period commencing after the Company has given such notice, each Fully Exercising Major Holder may, by giving notice to the Company, elect to purchase or acquire, in addition to the number of securities specified above, up to that portion of the New Securities for which Major Holders were entitled to subscribe but that were not

subscribed for by the Major Holders which is equal to the proportion that the Common Units issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of Preferred Units and any other Derivative Securities then held, by such Fully Exercising Major Holder bears to the Common Units issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Preferred Units and any other Derivative Securities then held, by all Fully Exercising Major Holders who wish to purchase such unsubscribed securities. The closing of any sale pursuant to this Section shall occur within the later of ninety (90) days of the date that the Offer Notice is given and the date of initial sale of New Securities pursuant to subsection (a) of this Section.

(d) If all New Securities referred to in the Offer Notice are not elected to be purchased or acquired as provided in subsection (b) of this Section, the Company may, during the ninety (90) day period following the expiration of the periods provided in subsection (b) of this Section (or such longer period as the Board determines to keep such offer open), offer and sell the remaining unsubscribed portion of such New Securities to any Person or Persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Offer Notice. If the Company does not enter into an agreement for the sale of the New Securities within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such New Securities shall not be offered unless first reoffered to the Major Holders in accordance with this Section.

(e) The right of first offer in this Section shall not be applicable to (i) Exempted New Securities; (ii) securities issued in the IPO (so long as all Major Holders have the same, pro rata, right to participate in any purchase thereof on the same terms); and (iii) the issuance of shares of Series B Preferred Units under the Series B Purchase Agreement.

(f) The covenants set forth in this Section shall terminate and be of no further force or effect (i) immediately before the consummation of the IPO, (ii) when the Company first becomes subject to the periodic reporting requirements of Section 12(g) or 15(d) of the Exchange Act, or (iii) upon a Deemed Liquidation Event, whichever event occurs first.

(g) For purposes of this Agreement, the term “Exempted New Securities” shall mean: (i) New Securities issued as a stock or unit dividend or other distribution or upon any subdivision, split or combination of the currently outstanding Units (or any such Units the original issuance of which was conducted in accordance with this Section); (ii) New Securities issued upon conversion, exchange or redemption of any currently outstanding convertible or exchangeable securities (or any New Securities the original issuance of which was conducted in accordance with this Section); (iii) New Securities issued upon exercise of any currently outstanding options or warrants (or any such options or warrants the original issuance of which was conducted in accordance with this Section); (iv) New Securities issued to any employee, former employee, consultant, financial or other advisor, Manager or advisory board member of the Company or any of its subsidiaries as compensation or as an incentive for services, including in connection with the implementation of the Transaction Bonus Plan pursuant to Section 5.1(d); (v) New Securities issued as consideration (whether partial or otherwise) for the purchase by the Company or any of its subsidiaries of assets constituting a business unit or of the stock or other equity securities of any Person or Persons; (vi) New Securities issued pursuant to a Public

Offering; (vii) New Securities issued in connection with the conversion of the Company from a limited liability company into a corporation; (viii) Units issued or issuable pursuant to the Series B Purchase Agreement or the common warrants issued thereunder (or upon conversion or exercise of any such Units or such common warrants); and (ix) New Securities designated by the Company, with the Required Preferred Consent, as being Exempted New Securities.

5.6 Conversion of Preferred Units.

(a) In General. Subject to the terms of this Section, each Preferred Unit outstanding shall, from and after the issue date of such Preferred Unit, be convertible, at the option of the holder thereof, at any time and from time to time, and without the payment of additional consideration by the holder thereof, into a number of Common Units equal to the fraction the numerator of which shall be the Original Issue Price for the Preferred Unit to be converted and the denominator of which shall be the Conversion Price applicable to the Preferred Unit to be converted in effect at the time of conversion. The “Conversion Price” shall mean, (i) for the Series A Preferred Units issued at either the Initial Closing or any Required Milestone Closing (as each such term is defined under the Series A Purchase Agreement) or pursuant to the CV Series A Warrant, $0.73527 (subject to adjustment from time to time as provided in this Section); (ii) for all other Series A Preferred Units, $0.85 (subject to adjustment from time to time as provided in this Section); and (iii) for the Series B Preferred Units, $0.70 (subject to adjustment from time to time as provided in this Section). In the event of a liquidation, dissolution or winding up of the Company or a Deemed Liquidation Event, the conversion rights hereunder with respect to the Preferred Units 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 holders of Preferred Units; provided that a holder of Preferred Units may elect to convert subject to, and conditioned upon, consummation of a Deemed Liquidation Event (notwithstanding anything herein to the contrary).

(b) Adjustment for Unit Splits and Combinations. If the Company shall at any time or from time to time after the date hereof effect a subdivision of the outstanding Common Units, the Conversion Price applicable to each series of Preferred Units in effect immediately before that subdivision shall be proportionately decreased so that the number of Common Units issuable on conversion of each such Unit shall be increased in proportion to such increase in the aggregate number of Common Units outstanding. If the Company shall at any time or from time to time after the date hereof combine the outstanding Common Units, the Conversion Price applicable to each series of Preferred Units in effect immediately before the combination shall be proportionately increased so that the number of Common Units issuable on conversion of each Preferred Unit shall be decreased in proportion to such decrease in the aggregate number of Common Units outstanding. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

(c) Adjustment of Conversion Prices Upon Issuance of Additional Common Units. In the event the Company shall at any time after the date hereof issue Additional Common Units (including Additional Common Units deemed to be issued pursuant to this Section), without consideration or for a consideration per Unit less than the then applicable

Conversion Price for any series of Preferred Units, then the Conversion Price applicable to such series of Preferred Units shall be reduced, concurrently with such issue, to a price (calculated to the nearest one-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:

(A) “CP₂” shall mean the Conversion Price applicable to such series of Preferred Units as in effect immediately after such issue of Additional Common Units;

(B) “CP₁” shall mean the Conversion Price applicable to such series of Preferred Units as in effect immediately prior to such issue of Additional Common Units;

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

(D) “B” shall mean the number of Common Units that would have been issued if such Additional Common Units 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

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

For purposes of this Section, the following definitions shall apply:

(i)

“Option” shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire Common Units or Convertible Securities.

(ii)

“Convertible Securities” shall mean any evidences of indebtedness, shares or other securities directly or indirectly convertible into or exchangeable for Common Units, but excluding Options.

(iii)

“Additional Common Units” shall mean all Common Units issued (or, pursuant to subsection (d) of this Section, deemed to be issued) by the Company after the date hereof, other than (i) the Preference Units outstanding as of the date hereof and all securities issued or issuable pursuant to the Series B Purchase Agreement or the Series B Bridge Warrants, in each case, at a price no less than the Original Series B Issue Price, and subject to an overall cap of $65,000,000 with respect to issued

Series B Preferred Units, and (ii) the following Common Units and (2) Common Units deemed issued pursuant to the following Options and Convertible Securities (clauses (i) and (ii), collectively, “Exempted Securities”):

(A) Common Units, Options or Convertible Securities issued as a dividend or distribution on Preferred Units;

(B) Common Units, Options or Convertible Securities issued by reason of a dividend, Unit split, split-up;

(C) Common Units (including any “profits interests” pursuant to Section 5.1(a)(ii)) 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 other issuance approved by the Board, or any Units issued pursuant to the Transaction Bonus Plan;

(D) Common Units or Convertible Securities actually issued upon the exercise of Options or Common Units actually issued upon the conversion or exchange of Convertible Securities, in each case provided such issuance is pursuant to the terms of such Option or Convertible Security;

(E) Common Units, 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 or acquisition or license of any assets or business, in each case as approved by the Board; or

(d) Deemed Issue of Additional Common Units

(i) If the Company at any time or from time to time after the date hereof shall issue any Options or Convertible Securities (excluding Options or Convertible Securities which are themselves Exempted Securities) 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 Units (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 Units 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.

(ii) If the terms of any Option or Convertible Security, the issuance of which resulted in an adjustment to the Conversion Price for any series of Preferred Units pursuant to the terms of subsection (c) of this Section, 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 (1) any increase or decrease in the number of Common Units issuable upon the exercise, conversion and/or exchange of any such Option or Convertible Security or (2) 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 applicable Conversion Price for each series of Preferred Units 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 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 (ii) shall have the effect of increasing the Conversion Price for any series of Preferred Units to an amount which exceeds the lower of (i) the Conversion Price for such series of Preferred Units 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 that would have resulted from any issuances of Additional Common Units (other than deemed issuances of Additional Common Units as a result of the issuance of such Option or Convertible Security) between the original adjustment date and such readjustment date.

(iii) If the terms of any Option or Convertible Security (excluding Options or Convertible Securities which are themselves Exempted Securities), the issuance of which did not result in an adjustment to the Conversion Price for any series of Preferred Units pursuant to the terms of subsection (c) of this Section (either because the consideration per share of the Additional Common Units subject thereto was equal to or greater than the applicable Conversion Price then in effect, or because such Option or Convertible Security was issued before the date hereof), are revised after the date hereof 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 (1) any increase in the number of Common Units issuable upon the exercise, conversion or exchange of any such Option or Convertible Security or (2) 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 Units subject thereto (determined in the manner provided in clause (i) above shall be deemed to have been issued effective upon such increase or decrease becoming effective.

(iv) 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 for any series of Preferred Units pursuant to the terms of subsection (c) of this Section, such Conversion Price shall be readjusted to such Conversion Price as would have obtained had such Option or Convertible Security (or portion thereof) never been issued.

(v) If the number of Common Units 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 for any series of Preferred Units provided for in this subsection (d) shall be effected at the time of such issuance or amendment based on such number of Units or amount of consideration without regard to any provisions for subsequent adjustments (and any subsequent adjustments shall be treated as provided in clauses (ii) and (iii) of this subsection (d)). If the number of Common Units 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 for any series of Preferred Units that would result under the terms of this subsection (d) 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 applicable Conversion Price that such issuance or amendment took place at the time such calculation can first be made.

(e) No Adjustment of Conversion Price. No adjustment to the Conversion Price for (x) the Series A Preferred Units shall be made as the result of the issuance or deemed issuance of Additional Common Units if the Company receives written notice from holders of Series A Preferred Units representing the Required Series A Consent; and (y) the Series B Preferred Units shall be made as the result of the issuance or deemed issuance of Additional Common Units if the Company receives written notice from holders of Series B Preferred Units representing the Required Series B Consent, in each case agreeing that no such adjustment shall be made as the result of the issuance or deemed issuance of such Additional Common Units.

(f) Multiple Closing Dates. In the event the Company shall issue on more than one date Additional Common Units that are a part of one transaction or a series of related transactions and that would result in an adjustment to the Conversion Price for any series of Preferred Units pursuant to the terms of subsection (c) of this Section, then, upon the final such issuance, the Conversion Price for such series of Preferred Units 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).

(g) Adjustment for Merger or Reorganization, etc. Subject to the provisions of this Agreement as it relates to a Deemed Liquidation Event, if there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving the Company in which the Common Units (but not the Preferred Units) are converted into or exchanged for securities, cash or other property (other than a transaction covered by subsection (b) of this Section), then, following any such reorganization, recapitalization, reclassification, consolidation or merger, each Preferred Unit shall thereafter be convertible in lieu of the Common Units 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 Common Units issuable upon conversion of the Preferred Units 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) shall be made in the application of the provisions in this Section with respect to the rights and interests thereafter of the holders of the Preferred Units, to the end that the provisions set forth in this Section (including provisions with respect to changes in and other adjustments of the Conversion Prices) 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 Units.

(h) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price for any series of Preferred Units pursuant to this Section, the Company at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of such series of Preferred Units a certificate setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property into which such series of Preferred Units are convertible) and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, as promptly as reasonably practicable after the written request at any time of any holder of Preferred Units (but in any event not later than 10 days thereafter), furnish or cause to be furnished to such holder a certificate setting forth (i) the Conversion Price applicable to such Preferred Units then in effect, and (ii) the number of Common Units and the amount, if any, of other securities, cash or property which then would be received upon the conversion of such Preferred Units.

(i) Notice of Record Date. In the event:

(A) the Company shall take a record of the holders of its Common Units (or other securities at the time issuable upon conversion of the Preferred Units) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right to subscribe for or purchase any Units or any other securities, or to receive any other security; or

(B) of any capital reorganization of the Company, any reclassification of the Common Units, or any Deemed Liquidation Event; or

then, and in each such case, the Company will send or cause to be sent to the holders of the Preferred Units a notice specifying, as the case may be, (i) the record date for such dividend, distribution or right, and the amount and character of such dividend, distribution or right, or (ii) the effective date on which such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up is proposed to take place, and the time, if any is to be fixed, as of which the holders of record of Common Units (or such other Units or securities at the time issuable upon the conversion of the Preferred Units) shall be entitled to exchange their Common Units (or such other Units or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up, and the amount per Unit and character of such exchange applicable to the Preferred Units and the Common Units. Such notice shall be sent at least 10 days prior to the record date or effective date for the event specified in such notice.

(j) No Fractional Units. No fractional Common Units shall be issued upon conversion of the Preferred Units. In lieu of any fractional Units to which the holder would otherwise be entitled, the Company shall pay cash equal to such fraction multiplied by the fair market value of one Common Unit as determined in good faith by the Board of Managers. Whether or not fractional Units would be issuable upon such conversion shall be determined on the basis of the total number of Preferred Units the holder is at the time converting into Common Units and the aggregate number of Common Units issuable upon such conversion.

(k) Mandatory Conversion.

(i) Upon either (a) the closing of a Qualified Public Offering, or (b) the date and time, or the occurrence of an event, specified in a written consent executed by Members holding Preferred Units representing the Required Series A Consent (including, for the avoidance of doubt, approval of each of CV II and Merck GHI so long as such party holds Preferred Units) (the time of such closing 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 “Mandatory Series A Conversion Time”), (i) all outstanding Series A Preferred Units shall automatically be converted into Common Units, at the then effective Conversion Price applicable to the Series A Preferred Units and (ii) such Units may not be reissued by the Company. Upon either (a) the closing of a Qualified Public Offering, or (b) the date and time, or the occurrence of an event, specified in a written consent executed by Members holding Preferred Units representing the Required Series B Consent (so long as such consent includes the approval of each of CV II and Merck GHI so long as such party holds Preferred Units) (the time of such closing 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 “Mandatory Series B Conversion Time” and, together with the Mandatory Series A Conversion Time, the “Mandatory Conversion Time”), (i) all outstanding Series B Preferred Units shall automatically be converted into Common Units, at the then effective Conversion Price applicable to the Series B Preferred Units and (ii) such Units may not be reissued by the Company.

(ii) All holders of record of Preferred Units shall be sent written notice of the Mandatory Conversion Time applicable to such Preferred Units and the place designated for mandatory conversion of all such Preferred Units pursuant to this Section. Such notice need not be sent in advance of the occurrence of the Mandatory Conversion Time. All rights with respect to the Preferred Units converted pursuant to this subsection, including the rights, if any, to receive notices and vote (other than as a holder of Common Units), will terminate at the applicable Mandatory Conversion Time, except only the rights of the holders thereof to receive the items provided for in the next sentence of this subsection. As soon as practicable after the applicable Mandatory Conversion Time, the Company shall reflect on its books and records the issuance to such holder, or to his, her or its nominees, of the number of full Common Units issuable on such conversion in accordance with the provisions hereof, together with cash as provided in subsection (j) in lieu of any fraction of a Common Unit otherwise issuable upon such conversion and the payment of any declared but unpaid distributions on the Preferred Units converted, without limiting Section 5.6(k)(iii). Such converted Preferred Units shall be retired and cancelled and may not be reissued, and the Company may thereafter take such appropriate action (without the need for Member action) as may be necessary to reduce the authorized number of Preferred Units accordingly.

(iii) In the event of a conversion of Preferred Units in connection with a Public Offering, each holder of Series A Preferred Units so converted shall be entitled to receive, in addition to the Common Units issuable upon conversion thereof, the form of which at the Company’s sole discretion either (i) a cash payment equal to the Fixed Series A Return in respect of such converted Series A Preferred Units, or (ii) Common Units (or shares of common stock, as applicable) with a value equal to the Fixed Series A Return in respect of such converted Series A Preferred Units (valuing such Common Units (or common stock) based on the closing price for such securities in the Public Offering). Such cash or securities shall be paid or issued by the Company upon the closing of such Public Offering.

ARTICLE VI

Capital Contributions and Capital Accounts

6.1 Capital Contributions; Capital Calls.

(a) Each Member has made, or shall make, the capital contribution, if any, and shall perform the commitment described in the subscription or other agreement entered into with the Company pursuant to which such Member acquired its Membership Interest.

(b) Except as provided in a separate agreement with such Member, no Member shall be required to make any additional contributions to the Company with respect to such Member’s Units. Except as expressly provided herein, no Member, in its capacity as a Member, shall have the right to receive any cash or any other property of the Company.

6.2 Capital Accounts.

(a) Maintenance Rules. The Company shall maintain for each Member a separate capital account (a “Capital Account”) in accordance with this Section 6.2(a). For the avoidance of doubt, each Warrant shall be treated as a Noncompensatory Option but shall not be treated as exercised upon issuance, and, therefore, each holder of a Warrant shall not (for purposes of the Warrant) be treated as a Member in the Company, and thus, the holder of a Warrant will not receive any allocation of income, gain, loss or deduction in respect of any Units underlying such Warrant until such Units are actually issued following exercise of such Warrant. Each Capital Account shall be maintained in accordance with the following provisions:

(i) Such Capital Account shall be increased by the cash amount or Book Value of any property contributed by such Member to the Company pursuant to this Agreement, such Member’s allocable share of Profits and any items in the nature of income or gains which are specially allocated to such Member pursuant to Section 8.2 or Section 8.3, and the amount of any liabilities of the Company assumed by such Member or which are secured by any property distributed to such Member.

(ii) Such Capital Account shall be decreased by the cash amount or Book Value of any property distributed to such Member pursuant to this Agreement, such

Member’s allocable share of Losses and any items in the nature of deductions or losses which are specially allocated to such Member pursuant to Section 8.2 or Section 8.3, and the amount of any liabilities of such Member assumed by the Company or which are secured by any property contributed by such Member to the Company.

(iii) If all or any portion of a Unit is transferred in accordance with the terms of this Agreement, the transferee shall succeed to the Capital Account of the transferor to the extent it relates to the transferred Unit (or portion thereof).

(iv) If (A) a new or existing Member contributes money or property to the Company (other than a de minimis amount as determined by the Board) as consideration for the issuance by the Company of any Units after the date hereof, (B) Units intended to constitute “profits interests” for services to be rendered for federal income tax purposes are issued, (C) the Company distributes more than a de minimis amount of Company assets other than cash as consideration for all or part of its Units, or (D) Preferred Units are converted into Common Units, (E) immediately prior to a Corporate Conversion pursuant to Section 11.7(a), or (F) Noncompensatory Options are issued, the Capital Accounts of the Members shall be adjusted in accordance with Treasury Regulation Section 1.704 1(b)(2)(iv)(f); provided, however, that in the event of the issuance of any Unit pursuant to the exercise of a Noncompensatory Option where the right to share in capital represented by such Unit differs from the consideration paid to acquire and exercise such option, the Book Value of Company assets immediately after the issuance of such Unit shall be adjusted upward or downward to reflect any unrealized gain or unrealized loss attributable to such assets and the Capital Accounts of the Members shall be adjusted in a manner consistent with Treasury Regulation Section 1.704-1(b)(2)(iv)(s); provided further, however, that in the event of an issuance of Units for a de minimis amount of cash or contributed property, in the event of an issuance of a Noncompensatory Option to acquire a de minimis amount of Units, or in the event of an issuance of a de minimis amount of Units as consideration for the provision of services, the Board may determine that such adjustments are unnecessary for the proper administration of the Company. If, upon the occurrence of an event described in this Section 6.2(a)(iv), a Noncompensatory Option of the Company is outstanding, the Company shall adjust the Book Value of each Company asset in accordance with Treasury Regulation Sections 1.704-1(b)(2)(iv)(f)(1) and 1.704-1(b)(2)(iv)(h)(2). In making such adjustments pursuant to a conversion of Preferred Units into Common Units, the Preferred Units shall be treated as convertible equity under Treasury Regulations Section 1.721-2(g)(3), and adjustments shall be made by subtracting the value of the conversion feature of the Preferred Units from Fair Market Value before adjusting the Book Value of Company assets as provided in Treasury Regulations Sections 1.704-1(b)(2)(iv)(h)(2) and 1.704-1(b)(2)(iv)(s).

The foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Section 1.704-1(b) of the Treasury Regulations and shall be interpreted and applied in a manner consistent with such Treasury Regulations. If the Board determines that it is prudent to modify the manner in which the Capital Accounts, or any increases or decreases to the Capital Accounts, are computed in order to comply with such Treasury Regulations, the Board may authorize such modifications.

(b) Definition of Profits and Losses. “Profits” and “Losses” mean, for each Taxable Year or other period, an amount equal to the Company’s taxable income or loss, respectively, for such Taxable Year or other period, determined in accordance with Code Section 703(a) (for this purpose, all items of income, gain, loss or deduction required to be stated separately pursuant to Code Section 703(a)(1) shall be included in taxable income or loss), with the following adjustments:

(i) The computation of all items of income, gain, loss and deduction shall include tax-exempt income and those items described in Treasury Regulation Section 1.704-1(b)(2)(iv)(i), without regard to the fact that such items are not includable in gross income or are not deductible for federal income tax purposes.

(ii) If the Book Value of any Company property is adjusted pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(e) or (f), the amount of such adjustment shall be taken into account as gain or loss from the disposition of such property.

(iii) Items of income, gain, loss or deduction attributable to the disposition of Company property having a Book Value that differs from its adjusted basis for tax purposes shall be computed by reference to the Book Value of such property.

(iv) Items of depreciation, amortization and other cost recovery deductions with respect to Company property having a Book Value that differs from its adjusted basis for tax purposes shall be computed by reference to the property’s Book Value in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(g).

(v) To the extent an adjustment to the adjusted tax basis of any Company property pursuant to Code Sections 732(d), 734(b) or 743(b) is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis).

6.3 Negative Capital Accounts. If any Member has a deficit balance in its Capital Account, such Member shall have no obligation to restore such negative balance or to make any Capital Contributions to the Company by reason thereof, and such negative balance shall not be considered an asset of the Company or of any Member.

6.4 No Withdrawal. No Member will be entitled to withdraw any part of his or its Capital Contribution or Capital Account or to receive any distribution from the Company, except as expressly provided in this Agreement.

6.5 Loans From Members. Loans by Members to the Company shall not be considered Capital Contributions.

6.6 Status of Capital Contributions.

(a) No Member shall receive any interest, salary or drawing with respect to its Capital Contributions or its Capital Account, except as otherwise specifically provided in this Agreement.

(b) Except as otherwise provided herein, no Member shall be required to lend any funds to the Company or to make any additional Capital Contributions to the Company. No Member shall have any personal liability for the repayment of any Capital Contribution of any other Member.

ARTICLE VII

Distributions

7.1 Generally.

(a) Subject to Sections 7.2, 7.3 and 4.9, the Board shall have sole discretion regarding the amounts and timing of distributions to Members in respect of the outstanding Units, in each case subject to the retention and establishment in good faith of reserves of, or payment to third parties of, such funds as it deems reasonably necessary with respect to the reasonable business needs of the Company which shall include the payment or the making of provision for the payment when due of the Company’s obligations, including the payment of any management or administrative fees and expenses or any other obligations, including any amounts payable under the Transaction Bonus Plan (the amount of cash on hand in excess of such reserves and other amounts at any given time being referred to herein as the “Available Cash”).

(b) Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not make any distribution to Members (x) if such distribution would violate Section 18-607 of the Delaware Act or other applicable law, or (y) to the extent that, immediately following such distribution, such Member’s Capital Account would be negative.

7.2 Interim Distributions. Subject to Sections 7.1(b), 7.3, 4.9 and 4.10, non-liquidating distributions of Available Cash or other assets (taking such other assets into account at their Fair Market Value at the time of distributions) shall be distributed, at such times and in such amounts as the Board determines in its sole discretion, to the Members in the following order and priority:

(a) First, to the holders of the outstanding Series B Preferred Units (to the extent not converted into Common Units at or prior to the date of any such distribution), on a per Unit basis, in an amount equal to the Series B Unreturned Capital Value with respect to all outstanding Series B Preferred Units. If upon any such distribution, the amount to be distributed shall be insufficient to pay the holders of the Series B Preferred Units the full amount to which they shall be entitled under this Section 7.2(a), the holders of the Series B Preferred Units shall share ratably in any such distribution in proportion to the respective amounts which would otherwise be payable in respect of such Units held by them upon such distribution if all amounts payable on or with respect to such Units pursuant to this Section 7.2(a) were paid in full;

(b) Second, to the holders of the outstanding Series A Preferred Units (to the extent not converted into Common Units at or prior to the date of any such distribution), on a per Unit basis, in an amount equal to the sum of (x) the Series A Unreturned Capital Value, and (y) the accrued and unpaid Series A Preferred Return with respect to all outstanding Series A Preferred Units. If upon any such distribution (after paying in full the amounts due the holders of the Series B Preferred Units under Section 7.2(a)) the remaining amount to be distributed shall be insufficient to pay the holders of the Series A Preferred Units the full amount to which they shall be entitled under this Section 7.2(b), the holders of the Series A Preferred Units shall share ratably in any such remaining distribution in proportion to the respective amounts which would otherwise be payable in respect of such Units held by them upon such distribution if all amounts payable on or with respect to such Units pursuant to this Section 7.2(b) were paid in full; and

(c) Thereafter, the balance of the proposed distribution shall be paid to all of the holders of Common Units and Preferred Units, on a per Unit basis (treating all Preferred Units on an as-if converted to Common Units basis); provided, that distributions to the holders of Common Units issued as profits interests shall be limited to a share of distributions attributable to profits and appreciation after such Common Units were granted.

7.3 Tax Advances. Subject to the restrictions of any of the Company’s and/or its subsidiaries’ then applicable debt financing agreements and subject to the retention of any other amounts necessary to satisfy the Company’s and/or the subsidiaries’ obligations, as close as is practicable to each date prescribed by the Code for an individual to pay quarterly installments of estimated tax, the Company shall distribute to each Member out of Available Cash, if any, cash in proportion to and to the extent of such Member’s Quarterly Estimated Tax Amount for the applicable calendar quarter. If, at any time after the final Quarterly Estimated Tax Amount has been distributed pursuant to the previous sentence with respect to any Fiscal Year, the aggregate Tax Advances to any Member with respect to such Fiscal Year are less than such Member’s Tax Amount for such Fiscal Year (a “Shortfall Amount”), the Company shall use commercially reasonable efforts to distribute cash in proportion to and to the extent of each Member’s Shortfall Amount. The Company shall use commercially reasonable efforts to distribute Shortfall Amounts with respect to a Fiscal Year before the 75th day of the next succeeding Fiscal Year (provided that if the Company has made distributions other than pursuant to this Section 7.3, the Board may apply such distributions to reduce any Shortfall Amount). If the aggregate distributions made to any Member pursuant to this Section 7.3 for any Fiscal Year exceed such Member’s Tax Amount (an “Excess Amount”) such Excess Amount shall reduce subsequent distributions that would be made to such Member pursuant to this Section 7.3, except to the extent taken into account as an advance pursuant to the next sentence. Distributions made pursuant to this Section 7.3 shall be taken into account as advances on distributions payable pursuant to Section 7.2, and shall (to the extent not previously taken into account pursuant to this sentence) reduce the distributions to be made to any Member under Section 7.2, when and as paid by the Company. No Member shall be liable to the Company for any amount distributed to it pursuant to this Section 7.3, or for any interest on such amount.

7.4 Indemnification and Reimbursement for Payments on Behalf of a Member. Except as otherwise provided in this Agreement, if the Company is required by law (as determined by the Tax Matters Person based on the advice of legal or tax counsel to the Company) to make any payment on behalf of a Member in its capacity as such (including in respect of withholding taxes, personal property taxes, and unincorporated business taxes, etc.), then such Member (the “Indemnifying Member”) will indemnify the Company in full for the entire amount paid, including interest, penalties and expenses associated with such payment. At the option of the Board, the amount to be indemnified may be charged against a Capital Account of the Indemnifying Member, and, at the option of the Board, either:

(a) promptly upon notification of an obligation to indemnify the Company, the Indemnifying Member will make a cash payment to the Company in an amount equal to the full amount to be indemnified (and the amount paid will be added to the Indemnifying Member’s Capital Account but will not be deemed to be a Capital Contribution), or

(b) the Company will reduce distributions which would otherwise be made to the Indemnifying Member until the Company has recovered the amount to be indemnified (and the amount of such reduction will be deemed to have been distributed for all purposes, but such deemed distribution will not further reduce the Indemnifying Member’s Capital Account).

A Member’s obligation to make contributions to the Company under this Section 7.4 will survive the termination, dissolution, liquidation and winding up of the Company, and for purposes of this Section 7.4, the Company will be treated as continuing in existence. The Company may pursue and enforce all rights and remedies it may have against each Member under this Section 7.4, including instituting a lawsuit to collect such contribution with interest calculated at a rate equal to the Company’s and its subsidiaries’ effective cost of borrowed funds.

7.5 Distributions Upon a Deemed Liquidation Event; Asset Sale. Subject to Section 7.1(b), unless the holders of (i) Preferred Units representing the Required Series A Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units) and the Required Series B Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units), and (ii) a majority of the outstanding Common Units (not including any Common Units issuable upon conversion of the Preferred Units), elect otherwise by written notice sent to the Company prior to the effective date of any Deemed Liquidation Event, the Company shall distribute the proceeds received by the Company in respect of such Deemed Liquidation Event in accordance with Section 10.2(b). Subject to Section 7.1(b), unless the holders of (i) Preferred Units representing the Required Series A Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units) and the Required Series B Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units), and (ii) a majority of the outstanding Common Units (not including any Common Units issuable upon conversion of the Preferred Units), elect otherwise by written notice sent to the Company, upon any sale or other transfer of a significant portion of its securities or sale, license and/or other transfer of a significant portion of its assets (which would not be deemed to be a Deemed Liquidation Event), the Company shall promptly distribute all of the Company’s Available Cash (after taking into account the proceeds (cash or otherwise) received in respect of any such transaction) to the Members in accordance with Section 7.2.

ARTICLE VIII

Allocations

8.1 Allocations of Profits and Losses. Subject to the other provisions of this Article VIII, the Company’s Profit and Loss for any fiscal period shall be allocated among the Members in such a manner that, as of the end of such fiscal period and to the extent possible, the Capital Account of each Member shall be equal to the respective net amount which would be distributed to such Member under this Agreement, determined as if the Company were to (a) liquidate the assets of the Company for an amount equal to their Fair Market Value as of the end of such fiscal period and (b) distribute the proceeds in liquidation in accordance with Section 10.2.

8.2 Regulatory and Special Allocations. Notwithstanding the provisions of Section 8.1:

(a) To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Code Section 734(b) or 743(b) is required to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated, as provided in Treasury Regulation Section 1.704-1(b)(2)(iv)(m), as an item of Profit (if the adjustment increases the basis of the asset) or Loss (if the adjustment decreases such basis) and such Profit or Loss shall be specially allocated to the Members in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations.

(b) If there is a net decrease in Company Minimum Gain (determined according to Treasury Regulation Section 1.704-2(d)(1)) during any Taxable Year, each Member shall be specially allocated Profits for such Taxable Year (and, if necessary, subsequent Taxable Years) in an amount equal to such Member’s share of the net decrease in Company Minimum Gain, determined in accordance with Treasury Regulation Section 1.704-2(g). The items to be so allocated shall be determined in accordance with Treasury Regulation Section 1.704-2(f)(6) and 1.704-2(j)(2). This paragraph is intended to comply with the minimum gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

(c) Member Nonrecourse Deductions shall be allocated in the manner required by Treasury Regulation Section 1.704-2(i). Except as otherwise provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Member Minimum Gain during any Taxable Year, each Member that has a share of such Member Minimum Gain shall be specially allocated Profits for such Taxable Year (and, if necessary, subsequent Taxable Years) in an amount equal to that Member’s share of the net decrease in Member Minimum Gain. Items to be allocated pursuant to this paragraph shall be determined in accordance with Treasury Regulation Section 1.704-2(i)(4) and 1.704-2(j)(2). This paragraph is intended to comply with the minimum gain chargeback requirements in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(d) In the event any Member unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), Profits shall be specially allocated to such Member in an amount and manner sufficient to

eliminate the Adjusted Capital Account Deficit created by such adjustments, allocations or distributions as quickly as possible. This paragraph is intended to comply with the qualified income offset requirement in Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(e) If, as a result of an exercise of a Noncompensatory Option, a Capital Account reallocation is required under Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), the Company shall make corrective allocations pursuant to Treasury Regulation Section 1.704-1(b)(4)(x).

(f) Nonrecourse Deductions for any Taxable Year or other period shall be specially allocated among the Members in proportion to their Percentage Interest in the Company.

(g) The allocations set forth in this Section above (the “Regulatory Allocations”) are intended to comply with certain requirements of the Treasury Regulations under Code Section 704. Notwithstanding any other provisions of this Article VIII (other than the Regulatory Allocations), the Regulatory Allocations shall be taken into account in allocating Profits and Losses among Members so that, to the extent possible, the net amount of such allocations of Profits and Losses and other items and the Regulatory Allocations to each Member shall be equal to the net amount that would have been allocated to such Member if the Regulatory Allocations had not occurred.

8.3 Curative Allocations. If the Tax Matters Person determines, after consultation with counsel experienced in income tax matters, that the allocation of any item of Company income, gain, loss, deduction or credit is not specified in this Article VIII (an “unallocated item”), or that the allocation of any item of Company income, gain, loss, deduction or credit hereunder is clearly inconsistent with the Members’ economic interests in the Company (determined by reference to the general principles of Treasury Regulation Section 1.704-1(b) and the factors set forth in Treasury Regulation Section 1.704-1(b)(3)(ii)) (a “misallocated item”), then the Board may allocate such unallocated items, or reallocate such misallocated items, to reflect such economic interests.

8.4 Tax Allocations.

(a) Subject to Section 8.4(g) below, all income, gains, losses, deductions and credits of the Company shall be allocated, for federal, state and local income tax purposes, among the Members in accordance with the allocation of such income, gains, losses, deductions and credits among the Members for computing their Capital Accounts, except that if any such allocation for tax purposes is not permitted by the Code or other applicable law, the Company’s subsequent income, gains, losses, deductions and credits shall be allocated among the Members for tax purposes, to the extent permitted by the Code and other applicable law, so as to reflect as nearly as possible the allocation set forth herein in computing their Capital Accounts. Each item of income, gain, loss, deduction and credit realized by the Company in any taxable year shall be allocated pro rata to the Members according to the amount of Profit or Loss, as the case may be, allocated to them in such year. Notwithstanding the foregoing, if as a result of the difference in timing of Capital Contributions by the Members to the Company and the contribution, loan or

other transfer by the Company to any of its subsidiaries of funds or other property contributed to the Company by such Members, the Company realizes short-term capital gain or both long-term and short-term capital gain for purposes of the Code, then the Tax Matters Person may allocate such short-term capital gain to the Members whose Capital Contributions resulted (directly or indirectly) in the recognition of such short-term capital gain.

(b) Items of Company taxable income, gain, loss and deduction with respect to any property contributed to the capital of the Company shall be allocated among the Members in accordance with Code Section 704(c) and the remedial method of Treasury Regulation Section 1.704-3(d), or such other method elected by the Tax Matters Person with the approval of Members holding (x) Preferred Units representing the Required Series A Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units) and the Required Series B Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units), and (y) a majority of the outstanding Common Units (not including any Common Units issuable upon conversion of the Preferred Units), so as to take account of any variation between the adjusted basis of such property to the Company for federal income tax purposes and its Book Value.

(c) If the Book Value of any Company property is adjusted pursuant to Section 6.2(a)(iv), subsequent allocations of items of taxable income, gain, loss and deduction with respect to such property shall take account of any variation between the adjusted basis of such property for federal income tax purposes and its Book Value in the same manner as under Code Section 704(c).

(d) Allocations of tax credit, tax credit recapture, and any items related thereto shall be allocated to the Members according to their interests in such items as determined by the Board taking into account the principles of Treasury Regulation Section 1.704-1(b)(4)(ii).

(e) Allocations pursuant to this Section 8.4 are solely for purposes of federal, state and local taxes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of Profits, Losses, distributions or other items pursuant to any provisions of this Agreement.

(f) Solely for the purpose of determining each Member’s share of Company “excess nonrecourse liabilities” pursuant to Treasury Regulation Section 1.752-3(a)(3), each Member’s interest in Company profits is hereby specified to be such Member’s Percentage Interest.

(g) To the extent permitted by the Code or other applicable law, notwithstanding anything contained herein to the contrary, allocations of taxable income realized by the Company as a result of distributions or dividends from (or redemptions of securities held by the Company of) any subsidiary, the proceeds of which are used to fund distributions to Members, shall be made to the Members receiving such distributions in proportion to such distributions.

ARTICLE IX

The Company will use reasonable efforts to deliver or cause to be delivered, by April 1 of each year, to each person who was a Member at any time during the previous Taxable Year, all information reasonably necessary for the preparation of such person’s United States federal income tax returns and any state, local and foreign income tax returns which such person is required to file as a result of the Company being engaged in a trade or business within such state, local or foreign jurisdiction, including a statement showing such person’s share of income, gains, losses, deductions and credits for such year for United States federal income tax purposes (and, if applicable, state, local or foreign income tax purposes).

9.4 Tax Elections. The Tax Matters Person will determine whether to make or revoke any available election (including the election provided under Code Section 754) for federal, state, local and foreign tax purposes. Each Member will upon request supply the information necessary to give proper effect to any such election.

9.5 Tax Controversies. (a) The Company’s Chief Executive Officer shall be the “tax matters partner” of the Company within the meaning of Section 6231(a)(7) of the Code, and as the “partnership representative” within the meaning of Section 6223(a) of the Code, as amended by the Revised Partnership Audit Procedures, and shall act in a similar capacity under any applicable non-U.S., state or local tax law (such person acting in such capacity, as the “Tax Matters Person”). In addition, if applicable, the Tax Matters Person shall appoint a designated individual through whom the partnership representative will act for all purposes of the Revised Partnership Audit Procedures as described in proposed Treasury Regulation Section 301.6223-1(b). With the consent of the Members holding a Majority in Interest, the Tax Matters Person shall represent the Company in any disputes, controversies or proceedings with the Internal Revenue Service (“IRS”) or with any state, local or non-U.S. taxing authority and subject to the provisions of this Section 9.5 is hereby authorized to exercise any and all authority and take any and all actions that it is permitted to take by applicable law when acting in that capacity. All reasonable expenses incurred by the Tax Matters Person while acting in the capacity of tax matters partner shall be paid or reimbursed by the Company; provided, however, that the Tax Matters Person shall not be entitled to a fee for acting as the Tax Matters Person.

(b) The Tax Matters Person shall promptly, after the receipt of any significant written communication from the IRS or any state or local tax authority in any administrative proceeding at the Company level with respect to the determination of any Company item of income, gain, loss, expense, deduction or credit, mail a copy of such communication to each Member (or former Member) potentially affected thereby including, without limitation, for any

tax period subject thereto, any communications under Section 6231(a) of the Code, as amended by the Revised Partnership Audit Procedures. The Tax Matters Person will use its commercially reasonable efforts to keep the other Members informed about significant developments in any U.S. federal, state or local income tax audit of the Company, and about any significant action that it shall take as the Tax Matters Person.

(c) Following a Member’s written request, the Tax Matters Person shall use commercially reasonable efforts to promptly furnish to such Member any information and documentation (including receipts or other proofs of payment of taxes) which is in the Tax Matters Person’s possession, or which the Tax Matters Person can obtain with the use of commercially reasonable efforts, and which is reasonably required by such Member (x) to comply in a timely manner with any U.S. federal, state or local tax filing or reporting requirements in respect of the Company or (y) to claim any available tax refunds or exemptions in respect of its share of the income of the Company, provided, that such Member shall be required to incur or bear any upfront or other third party or out of pocket cost or expense required in order to obtain any information or documentation requested by such Member.

(d) With the consent of the Members holding a Majority in Interest, and at the Company’s expense, the Tax Matters Person shall determine in good faith whether any elections under Sections 6221(b) and 6226(a) of the Code, as amended by the Revised Partnership Audit Procedures, shall be made. The financial burden of any imputed underpayment (as determined under Section 6225 of the Code, as amended by the Revised Partnership Audit Procedures) or other Tax assessment imposed on the Company and associated interest, adjustments to tax and penalties arising from an adjustment that are imposed on the Company shall be borne by the Members and former Members of the Company based on their proportionate interest in the Company during the applicable tax year under review.

(e) The Members agree to take all actions and provide any information reasonably requested by the Company or the Tax Matters Person to comply with the Revised Partnership Audit Procedures, including, where applicable, filing amended returns as provided in Sections 6225 or 6226 of the Code and providing confirmation thereof to the Tax Matters Person.

(f) This Section 9.5 shall apply to any comparable provision of state or local tax law, and shall survive the dissolution or termination of the Company and the withdrawal or other transfer of interests of or by any Member.

ARTICLE X

Dissolution and Liquidation

10.1 Dissolution. The Company shall be dissolved and its affairs wound up only upon the happening of any of the following events:

(a) Subject to Sections 4.9 and 4.10, upon the election to dissolve the Company by action of the Board and Members holding a Majority in Interest; or

(b) The entry of a decree of judicial dissolution under applicable law; provided, that, notwithstanding anything contained herein to the contrary, no Member shall make an application for the dissolution of the Company pursuant to applicable law without the approval of a Majority in Interest.

Dissolution of the Company shall be effective on the day on which the event occurs giving rise to the dissolution, but the Company shall not terminate until the winding up of the Company has been completed, the assets of the Company have been distributed as provided in Section 10.2 and the Certificate shall have been canceled.

10.2 Liquidation.

(a) Liquidator. Upon a liquidation, dissolution or winding up of the Company, the Board, with the approval of all Investor Managers, shall appoint a person or persons (or may designate the Board itself to so act) to act as the “Liquidator,” and such person(s) shall act as the Liquidator unless and until a successor Liquidator is appointed as provided in this Section 10.2. The Liquidator will agree not to resign at any time without 30 days’ prior written notice to the Board. The Liquidator may be removed at any time, with or without cause, by notice of removal and appointment of a successor Liquidator approved by the Board, with the approval of all Investor Managers. Any successor Liquidator will succeed to all rights, powers and duties of the former Liquidator. The right to appoint a successor or substitute Liquidator in the manner provided in Section 10.2 will be recurring and continuing for so long as the functions and services of the Liquidator are authorized to continue under the provisions of this Agreement, and every reference in this Agreement to the Liquidator will be deemed to refer also to any such successor or substitute Liquidator appointed in the manner provided in this Section 10.2. The Liquidator will receive compensation for its services as the Board may approve plus reimbursement of the Liquidator’s out-of-pocket expenses in performing its duties.

(b) Liquidating Actions. The Liquidator will liquidate the assets of the Company and apply and distribute the proceeds of such liquidation, in the following order of priority, unless otherwise required by mandatory provisions of applicable law:

(i) First, to the payment of the Company’s debts and obligations to its creditors (including Members), including sales commissions and other expenses incident to any sale of the assets of the Company, but not including any amounts payable under the Transaction Bonus Plan, if applicable, in order of the priority provided by law;

(ii) Second, to the establishment of and additions to such reserves as the Board, with the approval of all Investor Managers, deems necessary or appropriate; and

(iii) Thereafter, the balance of such proceeds shall be distributed to the Members in accordance with Section 7.2, after giving effect to all contributions, distributions and allocations for all periods, including the period during which such Liquidation occurs and taking into account any Transaction Bonus Plan.

The allocations and distributions provided for in this Agreement are intended to result in the Capital Account of each Member immediately prior to the distribution of the Company’s assets pursuant to this Section 10.2(b) being equal to the amount distributable to such Member pursuant to this Section 10.2(b).

(c) Distribution in Kind. Notwithstanding the provisions of Section 10.2(b) which require the liquidation of the assets of the Company, but subject to the order of priorities set forth in Section 10.2(b), if upon dissolution of the Company the Board (including with the approval of all Investor Managers) determines that an immediate sale of part or all of the Company’s assets would be impractical or could cause undue loss to the Members, the Board (including with the approval of all Investor Managers) may, in its sole discretion, defer the liquidation of any assets except those necessary to satisfy Company liabilities and reserves, and may, in its absolute discretion, distribute to the Members, in lieu of cash, as tenants in common and in accordance with the provisions of Section 10.2(b), undivided interests in such Company assets as the Liquidator deems not suitable for liquidation. Any such distribution in kind will be subject to such conditions relating to the disposition and management of such properties as the Liquidator deems reasonable and equitable and to any agreements governing the operating of such properties at such time. For purposes of any such distribution, the Board will determine the Fair Market Value of any property to be distributed in accordance with any valuation procedure which the Board reasonably deems appropriate.

(d) Reasonable Time for Winding Up. A reasonable time will be allowed for the orderly winding up of the business and affairs of the Company and the liquidation of its assets pursuant to Section 10.2(b) in order to minimize any losses otherwise attendant upon such winding up. Distributions upon liquidation of the Company (or any Member’s interest in the Company) and related adjustments will be made by the end of the Fiscal Year of the liquidation (or, if later, within 90 days after the date of such liquidation) or as otherwise permitted by Treasury Regulation Section 1.704-1(b)(2)(ii)(b).

(e) Termination. Upon completion of the distribution of the assets of the Company as provided in Section 10.2(b) hereof, the Company shall be terminated and the Liquidator shall cause the cancellation of the Certificate in the State of Delaware and of all qualifications and registrations of the Company as a foreign limited liability company in all applicable jurisdictions and shall take such other actions as may be necessary to terminate the Company.

ARTICLE XI

Transfer of Units

11.1 Restrictions. Each Member acknowledges and agrees that such Member shall not Transfer any Unit(s) except in accordance with the provisions of this Article XI. Any attempted Transfer in violation of the preceding sentence shall be deemed null and void for all purposes, and the Company will not record any such Transfer on its books or treat any purported transferee as the owner of such Unit(s) for any purpose.

11.2 General Restrictions on Transfer.

(a) Notwithstanding anything to the contrary in this Agreement, no transferee of any Unit(s) received pursuant to a Transfer shall become a Member in respect of or be deemed to have any ownership rights in the Unit(s) so Transferred unless the purported transferee is a Member prior to any such Transfer or is admitted as a Member as set forth in Section 11.3.

(b) Following a Transfer of any Unit(s) that is permitted under this Article XI, the transferee of such Unit(s) shall succeed to the Capital Account associated with such Unit(s) and shall receive allocations and distributions under Articles VI, VII, VIII and X in respect of such Unit(s). Notwithstanding the foregoing, Profits, Losses and other items will be allocated between the transferor and the transferee according to Code Section 706.

(c) Any Member who Transfers all of his or its Units (i) shall cease to be a Member upon such Transfer, and (ii) shall no longer possess or have the power to exercise any rights or powers of a Member of the Company.

(d) The Members acknowledge that certain of the Units issued to employees and consultants to the Company are subject to forfeiture to the Company under certain conditions as provided in a Unit Forfeiture or similar agreement between the applicable Member and the Company. No Member shall be permitted to transfer any Units subject to any such forfeiture right until such right lapses.

(e) Without limiting any provision herein set forth, no Member may Transfer (directly or indirectly, including by offering any of its securities, investing in any other Member or otherwise), any securities of the Company to another Member or any Affiliate thereof or any other third party unless such Member provides prior written notice to the Board (including the Investor Managers), unless such Transfer is a permitted transfer as defined for purposes of Section 11.6(d) hereto.

11.3 Procedures for Transfer. Subject in all events to the general restrictions on Transfers contained in this Article XI, no Transfer of Unit(s) may be completed until the prospective transferee is admitted as a Member of the Company by executing and delivering to the Company a written undertaking to be bound by the terms and conditions of this Agreement in a form acceptable to the Board. Upon the amendment of the Members Schedule by the Company, such prospective transferee shall be admitted as a Member and deemed listed as such on the books and records of the Company and thereupon the Company shall reissue the applicable Units in the name of such prospective transferee. The provisions of this Section 11.3 shall not apply with respect to the Transfer of any Unit(s) to a transferee that is a Member immediately prior to such Transfer.

11.4 Legend. Any certificates or instruments representing the Units will bear the following legend:

“THE TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE OR INSTRUMENT IS SUBJECT TO THE CONDITIONS SPECIFIED IN A LIMITED LIABILITY COMPANY AGREEMENT AMONG THE ISSUER AND ITS MEMBERS. A COPY OF SUCH LIMITED LIABILITY COMPANY AGREEMENT AS IN EFFECT FROM TIME TO TIME WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

11.5 Limitations.

Notwithstanding anything to the contrary in this Agreement, unless affirmatively waived in writing by the Board (including a majority of the disinterested Managers), no Unit may be Transferred and the Company may not issue any Unit unless (i) such Transfer or issuance, as the case may be, shall not affect the Company’s existence or qualification as a limited liability company under the state of its organization, (ii) such Transfer or issuance, as the case may be, shall not cause the Company to be classified as other than a partnership for United States federal income tax purposes (unless the Company has elected to be taxed as a corporation for federal income tax purposes), (iii) such Transfer or issuance, as the case may be, shall not result in a termination of the Company under Code Section 708; (iv) such Transfer or issuance, as the case may be, shall not cause the application of the tax-exempt use property rules of Code Sections 168(g)(l)(B) and 168(h) to the Company or its Members; and (v) such Transfer or issuance, as the case may be, shall be to a person or entity, or any of their Affiliates, who is not a competitor to the Company or an entity in which the Company holds a material interest, as reasonably determined by the Company, except this clause (v) shall not apply to a Transfer in connection with a Healthcare Trigger Event by Merck GHI.

11.6 Additional Transfer Restrictions.

(a) General. Subject to the other provisions of this Article XI, a Member may Transfer Units only if such Member has complied with the terms and requirements of Section 11.6(b), 11.6(c), 11.6(d) and 11.6(e), as applicable.

(b) Right of First Refusal. In the event that a Member (the “Transferring Member”) proposes to sell or otherwise Transfer (other than pursuant to a Public Offering or pursuant to an Approved Company Sale) any Units pursuant to a bona fide offer from a third party (the “Proposed Transferee”), the Transferring Member must first give the Major Holders (the “Non-Transferring Major Holders”) written notice (the “ROFR Notice”) of the number of Units to be transferred, the price, terms and conditions of the proposed sale, including the identity of the Proposed Transferee, and a copy of any written proposal, term sheet, letter of

intent or other agreement relating to the proposed sale. Within ten (10) days after the receipt of the ROFR Notice, the Non-Transferring Major Holders (or their assignees) may elect to purchase (as among themselves, pro rata in accordance with their respective Percentage Interests or in such other proportions as they shall agree; together with a pro rata right of oversubscription for all Major Holders who elect to purchase their full pro rata amount), and the Transferring Member agrees to sell to the Non-Transferring Major Holders (and their assignees), at the price and on the terms specified in the ROFR Notice, all or any portion of the Units as such Non-Transferring Major Holders (or their assignees) shall request (after taking into account such oversubscription rights). In the event the Non-Transferring Major Holders (or their assignees) elect to purchase all or part of the Units proposed to be transferred, the closing of such purchase will take place five (5) days after the expiration of such ten (10) day period or such other date as the parties shall agree. To the extent that the terms of payment set forth in the ROFR Notice consist of property other than cash against delivery, the Non-Transferring Major Holders (or their assignees) may substitute cash of equivalent value in lieu thereof. To the extent the Non-Transferring Major Holders (or their assignees) do not exercise in full this right of first refusal within the twenty (20) day period specified above (collectively, the “ROFR Notice Period”), the Transferring Member will have sixty (60) days thereafter to sell the Units not elected to be purchased by the Non-Transferring Major Holders (and their assignees) at the price and upon the terms and conditions no more favorable (in any material respect) to the purchasers of such Units than specified in the ROFR Notice. In the event the Transferring Member has not sold such Units within such sixty (60) day period, the Transferring Member may not thereafter sell any Units without first offering such Units to the Major Holders in the manner provided in this Section 11.6(b). The restrictions set forth in this Section 11.6(b) shall not apply in the following cases: (i) any Member may sell or transfer Units to the Company pursuant to a repurchase or similar right (including any transfer upon a forfeiture of Units pursuant to any subscription or similar agreement pursuant to which such shares were acquired); and (ii) any Member may sell or transfer any Units to a Permitted Transferee (as defined below) subject to Sections 11.3 and 11.5.

(c) Right of Co-Sale. To the extent that a Non-Transferring Major Holder does not elect to purchase all or part of the Units proposed to be transferred by the Transferring Member pursuant to subsection 11.6(b), then the Non-Transferring Major Holder shall have the right to participate in the proposed sale of Units to the Proposed Transferee on the same terms and conditions as specified in the ROFR Notice. The Non-Transferring Major Holder shall provide notice to the Transferring Member within ten (10) days after the receipt of the ROFR Notice indicating the number of Units that the Non-Transferring Major Holder wishes to sell under his, her or its right to participate. To the extent one or more of the Non-Transferring Major Holders exercises such right of participation in accordance with the terms and conditions of this Section 11.6(c), the number of Units that the Transferring Member may sell shall be correspondingly reduced. Each Non-Transferring Major Holder (a “Selling Major Holder”) may sell all or any part of that number of Units equal to the product obtained by multiplying (i) the aggregate number of Units covered by the ROFR Notice that have not been subscribed for pursuant to Section 11.6(b) by (ii) a fraction, the numerator of which is the number of Units owned by the Selling Major Holders on the date of the ROFR Notice and the denominator of which the total number of Units owned by all of the Selling Major Holders and the Transferring Member on the date of the ROFR Notice.

(d) Permitted Transfers; Healthcare Trigger Event. The restrictions contained in Sections 11.6(b) and Section 11.6(c) shall not apply with respect to any Transfer of Units by any Member (A) in the case of a Member who is an individual, pursuant to applicable laws of descent and distribution or, if such Transfer is made for bona fide estate planning purposes (which bona fide estate planning purposes, if requested by the Board, shall be verified by a legal opinion from counsel experienced in such matters), then to any Immediate Family Member of such Member, any entity controlled or under common control with such Member or a trust or similar vehicle established by such Member, (B) in the case of a non-individual Member, to its Affiliates or current or former stockholders, partners, including limited partners, or members; provided, in each case, that any such transferee shall have complied with the requirements of Section 11.3 and 11.5, or (C) in the case of Merck GHI, upon a HealthCare Trigger Event, as a condition precedent to such Healthcare Trigger Event and subject in all cases to applicable law, Merck GHI shall have the right, in its sole discretion, to transfer its Series A Preferred Units to a third party reasonably acceptable to the Company without the application of Sections 11.6(b) or 11.6(c). The Company will fully cooperate with such sale, including with respect to due diligence by any potential purchaser and the execution of any reasonably required documents and obtaining of reasonably necessary consents and waivers by existing Members. The transferees permitted by this Section 11.6(d) are referred to herein as “Permitted Transferees”.

(e) Approved Company Sale.

(i) If (A) the Board (if required by applicable law) and (B) the holders of (1) a Majority in Interest and (2) Members holding Preferred Units representing the Required Series A Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units) and the Required Series B Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units) (the “Selling Members”), approve a sale of all or substantially all of the Company’s assets determined on a consolidated basis or a sale of all (or a lesser percentage, if necessary, as determined by the Selling Members for accounting, tax or other reasons) of the Company’s outstanding Units or equivalents (in either case, whether by merger, recapitalization, consolidation, reorganization, combination or otherwise) or any other transaction which has the same effect as any of the foregoing, to an Independent Third Party or group of Independent Third Parties (each such sale or transaction, an “Approved Company Sale”), then each holder of Units will vote for, consent to and raise no objections against the Approved Company Sale or the process. If the Approved Company Sale is structured as a merger or consolidation, then each holder of Units shall waive any dissenter’ rights, appraisal rights or similar rights in connection with such merger or consolidation. If the Approved Company Sale is structured as a Transfer of Units, then each holder of Units shall agree to sell all of his or its Units and rights to acquire Units on the same terms and conditions, in all material respects, as applicable to the respective types of Units to be Transferred in such Approved Company Sale. Each holder of Units shall take all necessary or desirable actions in connection with the consummation of an Approved Company Sale as requested by the Board, including, without limitation, executing the applicable purchase agreement. If the Board, the Company or any of the holders of Units enter into any negotiation or transaction for which Rule 506 (or any similar rule then in effect) promulgated by the Securities and Exchange Commission may be available with respect to such negotiation or transaction (including a merger, consolidation or other reorganization), each holder of Units who is not an “accredited investor,” as that term is defined in Regulation D as promulgated under the Securities Act, will, at the

request of the Company, appoint either a purchaser representative (as such term is defined in Rule 501 under the Securities Act) designated by the Company, in which event the Company will pay the fees of such purchaser representative, or another purchaser representative (reasonably acceptable to the Company), in which event such holder will be responsible for the fees of the purchaser representative so appointed.

(ii) Notwithstanding the foregoing, no Member will be required to comply with Section 11.6(e)(i) above in connection with any proposed Approved Company Sale (the “Proposed Sale”) unless:

(A) the liability for indemnification, if any, of such Member in the Proposed Sale and for the inaccuracy of any representations and warranties made by the Company or its Members in connection with such Proposed Sale, is several and not joint with any other Person (except to the extent that funds may be paid out of an escrow established to cover breach of representations, warranties and covenants of the Company as well as breach by any Member of any of identical representations, warranties and covenants provided by all Members), and is pro rata in proportion to, and does not exceed, the amount of consideration paid to such Member in connection with such Proposed Sale; and

(B) upon the consummation of the Proposed Sale, (i) each holder of each class or series of the Company’s Units will receive the same form of consideration for their Units of such class or series as is received by other holders in respect of their Units of such same class or series, (ii) each holder of a series of Preferred Units will receive the same amount of consideration per share of such series of Preferred Units as is received by other holders in respect of their shares of such same series, (iii) each holder of Common Units will receive the same amount of consideration per Common Unit as is received by other holders in respect of their Common Units, and (iv) unless Members holding Preferred Units representing the Required Series A Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units) and the Required Series B Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units) elect to receive a lesser amount by written notice given to the Company at least ten (10) days prior to the effective date of any such Proposed Sale, the aggregate consideration receivable by all holders of the Preferred Units and Common Units shall be allocated among the holders of Preferred Units and Common Units on the basis of the relative liquidation preferences to which the holders of the Preferred Units and the holders of Common Units are entitled in a Deemed Liquidation Event (assuming for this purpose that the Proposed Sale is a Deemed Liquidation Event) in accordance with Section 10.2(b).

11.7 Initial Public Offering; Conversion to C Corporation.

(a) If at any time (A) the Board and (B) the holders of (1) a Majority in Interest and (2) subject to Section 11.7(b), Preferred Units representing the Required Series A Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units) and the Required Series B Consent (including the approval of each of CV II and Merck GHI so long as such party holds Preferred Units), desire to cause (i) a transfer of all or a substantial portion of (x) the assets of the Company or any of its subsidiaries or (y) the Units, to a newly organized corporation or other business entity (“Newco”), (ii) a merger or consolidation of the Company or any of its subsidiaries into or with a Newco as provided under Section 18-209 of the Delaware Act or otherwise, (iii) a conversion of the Company to a corporation pursuant to Section 18-214 of the Delaware Act or otherwise, (iv) another restructuring of all or substantially all of the assets or Units of the Company into a Newco, including by way of the conversion of the Company into a Delaware corporation (any such corporation, also “Newco”), in any case in anticipation of or otherwise in connection with a registered initial public offering of securities of a Newco (an “Initial Public Offering”) or for any other bona fide business reason, each Member shall take such steps to effect such transfer, merger, consolidation, distribution or other restructuring as may be requested by the Board, including, without limitation, transferring or tendering such Member’s Units to a Newco in exchange or consideration for shares of capital stock or other equity interests of Newco, determined in accordance with the valuation procedures set forth in Section 11.7(b).

(b) In connection with a transaction described in Section 11.7(a) (a “Corporate Conversion”), (1) the Units (including Preferred Units) shall be exchanged, converted into or redeemed for shares with substantially equivalent economic, governance, priority and other rights and privileges as in effect immediately prior to such Corporate Conversion (including without limitation board size and composition and voting and approval rights and liquidation preferences), and except as otherwise approved by the Board, (2) each holder of outstanding Units issued as “profits interest” (a “PI Holder”) shall be converted or exchanged for (x) shares of common stock of Newco in an amount equal to the Capital Account balance of such PI Holder associated with such Units (after taking into account the adjustment to Capital Accounts to reflect Book Value pursuant to Section 6.2(a)(iv)) divided by the fair market value of one share of common stock (the “Per Share FMV”) of Newco (such number of shares being referred to herein as the “New Common Shares”), and (y) for each PI Holder who at such time is an employee or active consultant to the Company, a stock option grant for a number of shares of common stock of Newco equal to the total number of outstanding Units issued as “profits interest” then held by such PI Holder minus the New Common Shares (such number subject to an appropriate adjustment for any stock split, stock combination or similar event in connection with the Corporate Conversion), with an exercise price per common share equal to the Per Share FMV (and with all such securities subject to identical vesting and similar restrictions). In connection with a Corporate Conversion, the Board shall cause Newco to enter into such agreements and adopt a certificate of incorporation and bylaws as are necessary to provide the Members with rights with respect to such corporation which are substantially similar to the rights of such Members pursuant to this Agreement as mutually agreed upon by the Company, CV II and Merck GHI. Notwithstanding anything herein to the contrary, including, without limitation, Sections 4.9 and 4.10 and Section 11.7(a)((B)(2), neither the Required Series A Consent nor the Required Series B Consent, nor the consent of either CV II or Merck GHI, shall be required in connection with any Corporate Conversion that is in anticipation of (and conditioned upon) a Qualified Public Offering and that satisfies the conditions of this Section 11.7(b) (including the preceding sentence).

(c) Each Member hereby agrees (i) not to effect any sale or distribution of any Common Units (or any equity securities issued in exchange for, or distributed with respect to, Common Units, including any equity securities of Newco) or any securities convertible into or exchangeable or exercisable for Common Units (or any equity securities issued in exchange for, or distributed with respect to, Common Units, including any equity securities of Newco), during the seven days prior to and the 180-day period beginning on the effective date of an Initial Public Offering (except as part of such Initial Public Offering, if otherwise permitted), unless the underwriters managing such Initial Public Offering otherwise agree (which agreement shall be equally applicable to all Members) and (ii) to execute and deliver any reasonable agreement which is consistent with the provisions of this Section and which may be required by the underwriters managing such Initial Public Offering.

(d) Each Member hereby makes, constitutes and appoints the Company, with full power of substitution and resubstitution, its true and lawful attorney, for it and in its name, place and stead and for its use and benefit, to act as its proxy in respect of any vote or approval of Members required to give effect to this Section, including any vote or approval required under Section 18-209 of the Delaware Act. The proxy granted pursuant to this Section is a special proxy coupled with an interest and is irrevocable.

If any time period for giving notice or taking action under this Agreement expires on a day which is a Saturday, Sunday or holiday in the state in which the Company’s chief executive office is located, the time period shall be automatically extended to the business day immediately following such Saturday, Sunday or holiday.

12.12 Waiver of Jury Trial. EACH PARTY TO THIS AGREEMENT HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LAW, TRIAL BY JURY IN ANY LITIGATION IN ANY COURT WITH RESPECT TO, IN CONNECTION WITH, OR ARISING OUT OF THIS AGREEMENT OR THE VALIDITY, PROTECTION, INTERPRETATION, COLLECTION OR ENFORCEMENT THEREOF.

12.13 No Strict Construction. The parties to this Agreement have participated jointly in the negotiation and drafting of this Agreement.

Except as otherwise expressly set forth in this Agreement, this Agreement and the other agreements referred to in this Agreement embody the complete agreement and understanding among the parties to this Agreement with respect to the subject matter of this Agreement and supersedes and preempts any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter of this Agreement in any way.

12.15 Parties in Interest. Nothing herein shall be construed to be to the benefit of or enforceable by any third party including, but not limited to, any creditor of the Company.

12.16 Arbitration Except as specifically provided herein, any dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration, conducted before a single arbitrator (to be mutually agreed upon) in the State of New Jersey, in accordance with the rules of the American Arbitration Association then in effect. If the parties cannot agree on a single arbitrator, each party shall appoint one arbitrator who shall then jointly appoint a single arbitrator. Judgment shall be final and may be entered on the arbitrator’s award in any court having jurisdiction. The arbitrator shall have the authority to allocate between the parties the expense of any such arbitration based on his determination of the relative fault, if any, of the parties. The parties may enforce any final determination in any state or federal court having jurisdiction over the dispute. For the purpose of any action or proceeding instituted with respect to any final determination, the parties hereby irrevocably submits to the jurisdiction of such courts, irrevocably consents to the service of process by registered mail or personal service and hereby irrevocably waives, to the fullest extent permitted by law, any objection which he may have or hereafter have as to personal jurisdiction, the laying of the venue of any such action or proceeding brought in any such court and any claim that any such action or proceeding brought in any court has been brought in an inconvenient form.
