FOURTH AMENDED AND RESTATED

CERTIFICATE OF INCORPORATION

RADIUS HEALTH, INC.

(Pursuant to Section 242 and 245 of the

General Corporation Law of the State of Delaware)

Radius Health, Inc., a Delaware corporation hereby certifies as follows:

1. The name of the corporation is Radius Health, Inc. (the “Corporation”). The Corporation filed its original Certificate of Incorporation with the Secretary of State of the State of Delaware on October 3, 2003 and the name under which it was originally incorporated was NuVios, Inc.

2. This Fourth Amended and Restated Certificate of Incorporation (the “Certificate”) amends, restates and integrates the provisions of the Third Amended and Restated Certificate of Incorporation as heretofore in effect (the “Prior Certificate”), has been duly adopted in accordance with the provisions of Sections 242 and 245 of the General Corporation Law of the State of Delaware (“DGCL”), and has been approved by written consent of the stockholders of the Corporation in accordance with the provisions of Section 228 of the DGCL (prompt notice of such action having been given to those stockholders who did not consent in writing).

3. Effective immediately at the effective date of the filing of this Certificate (the “Effective Time”), the Prior Certificate, as heretofore amended, is hereby further amended and restated to read in its entirety as follows:

ARTICLE I
Name

The name of the corporation is Radius Health, Inc.

ARTICLE II
Purpose

The Corporation is organized to engage in any lawful act or activity for which a corporation may be organized under the DGCL.

ARTICLE IIA
Reverse Split

Simultaneously with the Effective Time (the “Split Effective Date”), a reverse split (the “Reverse Split”) of the Corporation’s outstanding capital stock shall occur as follows: (a) each share of Common Stock issued and outstanding or held as treasury shares immediately prior to the Split Effective Date (the “Old Common Stock”) shall automatically without any action on the part of the holder thereof, be reclassified and changed into 0.06666667 of one share of Common Stock from and after the Split Effective Date (the “New Common Stock”), (b) each share of Series A Stock issued and outstanding or held as treasury shares immediately prior to the Split Effective Date (the “Old Series A Stock”) shall automatically without any action on the part of the holder thereof, be reclassified and changed into

0.06666667 of one share of Series A Stock from and after the Split Effective Date (the “New Series A Stock”), (c) each share of Series B Stock issued and outstanding or held as treasury shares immediately prior to the Split Effective Date (the “Old Series B Stock”) shall automatically without any action on the part of the holder thereof, be reclassified and changed into 0.06666667 of one share of Series B Stock from and after the Split Effective Date (the “New Series B Stock”) and (d) each share of Series C Stock issued and outstanding or held as treasury shares immediately prior to the Split Effective Date (the “Old Series C Stock”) shall automatically without any action on the part of the holder thereof, be reclassified and changed into 0.06666667 of one share of Series C Stock from and after the Split Effective Date (the “New Series C Stock”).

With respect to dividends, Liquidation and Event of Sale prior, the Series A Stock, Series B Stock and Series C Stock shall rank senior and prior to the Corporation’s Common Stock and to all other classes or series of stock issued by the Corporation, except as otherwise approved by the affirmative vote or consent of the holders shares of Existing Senior Preferred Stock representing at least a majority of the shares of the voting power of the Existing Senior Preferred Stock then outstanding (determined as set forth in the second sentence of Section A.6(a) hereof) (the “Existing Senior Majority”).

3. Dividend Provisions.

(a) Series C Stock. The holders of shares of the Series C Stock shall be entitled to receive dividends at the rate of 8% of the Series C Original Purchase Price (as defined in Section A.8 hereof) per annum, compounding annually, and which will accrue on a quarterly basis commencing on the applicable date of issuance of each of such shares of Series C Stock. The holders of Series C Stock shall be entitled to receive dividends prior in right to the payment of dividends and other distributions (whether in cash, property or securities of the Corporation, including subscription or other rights to acquire securities of the Corporation) on the Series B Stock, Series A Stock and Common Stock. Dividends hereunder shall be payable in cash, when, as and if declared or paid by the Board of Directors and, as accrued, on any Liquidation (as defined in Section A.4(b) hereof) or Event of Sale (as defined in Section A.4(h)(vii) hereof), or upon any Redemption Date (as defined in Section A.5(c) hereof). Dividends hereunder shall be payable in shares of Common Stock (calculated based upon the then effective Series C Conversion Price), as accrued, upon the conversion of the Series C Stock into Common Stock. Whenever any dividend may be declared or paid on any shares of Series C Stock, the Board of Directors shall also declare and pay a dividend on the same terms, at the same rate and in like kind upon each other share of the Series C Stock then outstanding, so that all outstanding shares of Series C Stock

will participate equally with each other and ratably per share (calculated as provided in Section A.3(d) hereof). Whenever any dividend or other distribution, whether in cash or property or in securities of the Corporation (or subscription or other rights to purchase or acquire securities of the Corporation), may be declared or paid on: (i) any shares of the Common Stock, the Board of Directors shall also declare and pay a dividend on the same terms, at the same rate and in like kind upon each share of the Series C Stock then outstanding so that all outstanding shares of Series C Stock will participate in such dividend ratably with such shares of Common Stock (calculated as provided in Section A.3(d) hereof); or (ii) any shares of any other series of Preferred Stock, the Board of Directors shall also declare and pay a dividend on the same terms, at the same or equivalent rate upon each share of the Series C Stock then outstanding so that all outstanding shares of Series C Stock will participate in such dividend ratably with such shares of such other series of Preferred Stock (based on the number of shares of Common Stock into which each share Series C Stock and each share of such other series of Preferred Stock is then convertible, if applicable, or, otherwise, the relative liquidation preference per share, of such other series of Preferred Stock as compared with the Series C Stock then outstanding).

(b) Series B Stock. Following payment in full of required dividends to the holders of Series C Stock in accordance with Section A.3(a) above, the holders of shares of the Series B Stock shall be entitled to receive dividends at the rate of 8% of the Series B Original Purchase Price (as defined in Section A.8 hereof) per annum, compounding annually, and which will accrue on a quarterly basis commencing on the applicable date of issuance of each of such shares of Series B Stock. The holders of Series B Stock shall be entitled to receive dividends prior in right to the payment of dividends and other distributions (whether in cash, property or securities of the Corporation, including subscription or other rights to acquire securities of the Corporation) on the Series A Stock and Common Stock. Dividends hereunder shall be payable in cash, when, as and if declared or paid by the Board of Directors and, as accrued, on any Liquidation (as defined in Section A.4(b) hereof) or Event of Sale (as defined in Section A.4(h) hereof), or upon any Redemption Date (as defined in Section A.5(c) hereof). Dividends hereunder shall be payable in shares of Common Stock (calculated based upon the then effective Series B Conversion Price), as accrued, upon the conversion of the Series B Stock into Common Stock. Whenever any dividend may be declared or paid on any shares of Series B Stock, the Board of Directors shall also declare and pay a dividend on the same terms, at the same rate and in like kind upon each other share of the Series B Stock then outstanding, so that all outstanding shares of Series B Stock will participate equally with each other and ratably per share (calculated as provided in Section A.3(d) hereof). Whenever any dividend, whether in cash or property or in securities of the Corporation (or subscription or other rights to purchase or acquire securities of the Corporation), may be declared or paid on: (i) any shares of the Common Stock, the Board of Directors shall also declare and pay a dividend on the same terms, at the same rate and in like kind upon each share of the Series B Stock then outstanding so that all outstanding shares of Series B Stock will participate in such dividend ratably with such shares of Common Stock (calculated as provided in Section A.3(d) hereof); or (ii) any shares of Series A Stock, the Board of Directors shall also declare and pay a dividend on the same terms, at the same or equivalent rate upon each share of the Series B Stock then outstanding so that all outstanding shares of Series B Stock will participate in such dividend ratably with such shares of Series A Stock (based on the number of shares of Common Stock into which each share of Series B Stock and each share of Series A Stock is then convertible, if applicable, or, otherwise, the relative liquidation preference per share, of Series A Stock as compared with the Series B Stock then outstanding).

(c) Series A Stock. Following payment in full of required dividends to the holders of Series C Stock and Series B Stock in accordance with Sections A.3(a) and (b) above, the holders of shares of the Series A Stock shall be entitled to receive, when, if and as declared by the Board of Directors, dividends on any shares of Series A Stock, out of funds legally available for that purpose, at a rate to be determined by the Board of Directors if and when they may so declare any dividend on the Series A Stock.

(d) In connection with any dividend declared or paid hereunder, each share of Existing Preferred Stock shall be deemed to be that number of shares (including fractional shares) of Common Stock into which it is then convertible, rounded up to the nearest one-tenth of a share. No fractional shares of capital stock shall be issued as a dividend hereunder. The Corporation shall pay a cash adjustment for any such fractional interest in an amount equal to the fair market value thereof on the last Business Day (as defined in Section A.8 hereof) immediately preceding the date for payment of dividends as determined by the Board of Directors in good faith.

4. Liquidation Rights.

(a) With respect to rights on Liquidation (as defined in Section A.4(b) hereof): (i) the shares of Series C Stock shall rank equally with each other and senior and prior to the shares of Series B Stock, Series A Stock and the Common Stock and to all other classes or series of stock issued by the Corporation, except as otherwise approved by the affirmative vote or consent of the Existing Senior Majority; (ii) the shares of Series B Stock shall rank equally with each other and senior and prior to the shares of Series A Stock and the shares of Common Stock and to all other junior classes or series of stock issued by the Corporation, and junior to the Series C Stock; and (iii) the Series A Stock shall rank senior and prior to the Corporation’s Common Stock and to all other junior classes or series of stock issued by the Corporation, and junior to the Existing Senior Preferred Stock.

(b) In the event of any liquidation, dissolution or winding-up of the affairs of the Corporation (collectively, a “Liquidation”): (i) the holders of shares of Series C Stock then outstanding (the “Series C Stockholders”) shall be entitled to receive out of the assets of the Corporation legally available for distribution to its stockholders, whether from capital, surplus or earnings, before any payment shall be made to the holders of Series B Stock then outstanding (the “Series B Stockholders”), the holders of Series A Stock then outstanding (the “Series A Stockholders,” and collectively with the Series C Stockholders and the Series B Stockholders, the “Existing Preferred Stockholders”), or the holders of Common Stock or any other class or series of stock ranking on Liquidation junior to such Series C Stock, an amount per share equal to the Series C Original Purchase Price (as defined in Section A.8 hereof), plus an amount equal to any declared or accrued but unpaid dividends thereon, calculated pursuant to Section A.3(a) hereof; (ii) after the distribution to the Series C Stockholders of the full amount to which they are entitled to receive pursuant to this Section A.4(b), the Series B Stockholders shall be entitled to receive out of the assets of the Corporation legally available for distribution to its stockholders, whether from capital, surplus or earnings, before any payment shall be made to the Series A Stockholders or the holders of Common Stock or any other class or series of stock ranking on Liquidation junior to such Series B Stock, an amount per share equal to the Series B Original Purchase Price (as defined in Section A.8 hereof), plus an amount equal to any declared or accrued but unpaid dividends thereon, calculated pursuant to Section A.3(b) hereof; and (iii) after the distribution to the Series B Stockholders of the full amount to which they are entitled to receive pursuant to this Section A.4(b), the Series A Stockholders shall be entitled to receive out of the assets of the Corporation legally available for distribution to its stockholders, whether from capital, surplus or earnings, before any payment shall be made to the holders of Common Stock or any other class or series of stock ranking on Liquidation junior to such Series A Stock, an amount per share equal to the Series A Original Purchase Price (as defined in Section A.8 hereof), plus an amount equal to any declared but unpaid dividends thereon, calculated pursuant to Section A.3(c) hereof. Notwithstanding the foregoing or anything else expressed or implied herein, the transactions contemplated by that certain Agreement and Plan of Merger dated as of April 25, 2011 by and among the Corporation, MPM Acquisition Corp. and RHI Merger Corp. (the “Merger Agreement”) shall not be a “Liquidation” for purposes of this Certificate.

(c) If, upon any Liquidation the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series C Stockholders the full amount to which each of

them shall be entitled pursuant to Section A.4(b) above, then the Series C Stockholders shall share ratably in any distribution of assets according to the respective amounts which would be payable to them in respect of the shares of Series C Stock held upon such distribution if all amounts payable on or with respect to such shares were paid in full.

(d) If, upon any Liquidation the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series B Stockholders the full amount to which each of them shall be entitled pursuant to Section A.4(b) above, then after payment to the Series C Stockholders of the full amount to which such stockholders are entitled pursuant to Section A.4(b) above, the Series B Stockholders shall share ratably in any remaining distribution of assets according to the respective amounts which would be payable to them in respect of the shares of Series B Stock held upon such distribution if all amounts payable on or with respect to such shares were paid in full.

(e) If, upon any Liquidation the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the Series A Stockholders the full amount to which each of them shall be entitled pursuant to Section A.4(b) above, then after payment to the Series C Stockholders and Series B Stockholders of the full amount to which such stockholders are entitled pursuant to Section A.4(b) above, the Series A Stockholders shall share ratably in any remaining distribution of assets according to the respective amounts which would be payable to them in respect of the shares of Series A Stock held upon such distribution if all amounts payable on or with respect to such shares were paid in full.

(f) In the event of any Liquidation, after payment shall have been made to the Existing Preferred Stockholders of the full amount to which they shall be entitled pursuant to Section A.4(b), the holders of each other class or series of capital stock (other than Common Stock) ranking on Liquidation junior to such Series C Stock, Series B Stock and Series A Stock (in descending order of seniority), but senior to the Common Stock, as a class, shall be entitled to receive an amount equal (and in like kind) to the aggregate preferential amount fixed for each such junior class or series of capital stock. If, upon any Liquidation prior to the Initial Closing of the Qualified Financing, after payment shall have been made to the Existing Preferred Stockholders of the full amount to which they shall be entitled pursuant to Section A.4(b), the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay a class or series of capital stock (other than the Common Stock) junior to the Series C Stock, Series B Stock and Series A Stock the full amount to which they shall be entitled pursuant to the preceding sentence, the holders of such other class or series of capital stock shall share ratably, based upon the number of then outstanding shares of such other class or series of capital stock, in any remaining distribution of assets according to the respective preferential amounts fixed for such junior class or series of capital stock or which would be payable to them in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full.

(g) In the event of any Liquidation prior, after payments shall have been made first to the Existing Preferred Stockholders and then to the holders of each junior class or series of capital stock (other than Common Stock) which is junior to the Series C Stock, Series B Stock and the Series A Stock but senior to the Common Stock, of the full amount to which they each shall be entitled as aforesaid, the holders of Common Stock, as a class, shall be entitled to share ratably with the Series C Stockholders and Series B Stockholders (calculated with respect to such Series C Stock and Series B Stock as provided in the last sentence in this Section A.4(g)) in all remaining assets of the Corporation legally available for distribution to its stockholders. For purposes of calculating the amount of any payment to be paid upon any such Liquidation pursuant to the participation feature described in this Section A.4(g), each share of such Existing Senior Preferred Stock shall be deemed to be that number of shares (including fractional shares and any shares attributable to the payment of accrued and unpaid

dividends upon conversion of such Preferred Stock pursuant to Section A.7(b)) of Common Stock into which it is then convertible, rounded to the nearest one-tenth of a share.

(h) (i) In the event of and simultaneously with the closing of an Event of Sale (as hereinafter defined), the Corporation shall, unless waived by the Existing Senior Majority or otherwise prevented by law, redeem all of the shares of Series C Stock, Series B Stock and Series A Stock then outstanding for a cash amount per share determined as set forth below in this Section A.4(h) hereof (the “Special Liquidation Price,” said redemption being referred to herein as a “Special Liquidation”). In the event the Event of Sale involves consideration that does not consist of cash, then the Special Liquidation Price may be paid with such consideration having a value equal to the Special Liquidation Price. To the extent there is any cash consideration in connection with an Event of Sale, at the option of the holders of a majority of the Series C Stock, the cash consideration will first (i) be applied to satisfy the Special Liquidation Price payable to the Series C Stockholders (in relative proportion to the full liquidation preference the Series C Stockholders would have received had there been sufficient cash consideration to have paid their liquidation preference in full); then (ii) be applied to satisfy the Special Liquidation Price payable to the holders of Series B Stock (in relative proportion to the full liquidation preference the Series B Stockholders would have received had there been sufficient cash consideration to have paid their liquidation preference in full), prior to the payment thereof to any other stockholders of the Corporation; and (iii) then be applied to satisfy the Special Liquidation Price payable to the holders of Series A Stock (in relative proportion to the full liquidation preference the Series A Stockholders would have received had there been sufficient cash consideration to have paid their liquidation preference in full), prior to the payment thereof to any other stockholders of the Corporation. For all purposes of this Section A.4(h), the Special Liquidation Price shall be equal to that amount per share which would be received by each Existing Preferred Stockholder if, in connection with an Event of Sale, all the consideration paid in exchange for the assets or the shares of capital stock (as the case may be) of the Corporation were actually paid to and received by the Corporation and the Corporation were immediately thereafter liquidated and its assets distributed pursuant to Sections A.4(a) through (h) hereof. To the extent that one or more redemptions (as described in Section A.5 hereof) and/or Special Liquidations are occurring concurrently, the Special Liquidation under this Section A.4(h) shall be deemed to occur first. The date upon which the Special Liquidation shall occur is sometimes referred to herein as the “Special Liquidation Date”.

(ii) In the absence of an applicable waiver pursuant to Section A.4(h)(i) above, at any time on or after the Special Liquidation Date, an Exisiting Preferred Stockholder shall be entitled to receive the Special Liquidation Price for each such share of Series C Stock, Series B Stock or Series A Stock owned by such holder. Subject to the provisions of Section A.4(h)(iii) hereof, payment of the Special Liquidation Price will be made to each such holder upon actual delivery to the Corporation or its transfer agent of the certificate of such holder representing such shares of Series A Stock, Series B Stock or Series C Stock, as the case may be, or an affidavit of loss as to the same.

(iii) If on the Special Liquidation Date less than all the shares of either Series C Stock, Series B Stock or Series A Stock then outstanding may be legally redeemed by the Corporation, the Special Liquidation shall be made first as to the Series C Stock pro rata with respect to such Series C Stock based upon the number of outstanding shares of Series C Stock then owned by each such holder thereof until such holders are satisfied in full, then to the holders of the Series B Stock pro rata with respect to such Series B Stock based upon the number of outstanding shares of Series B Stock then owned by each holder thereof, and then to the holders of the Series A Stock pro rata with respect to such Series A Stock based upon the number of outstanding shares of Series A Stock then owned by each holder thereof.

(iv) On and after any Special Liquidation Date, all rights in respect of the shares of Existing Preferred Stock to be redeemed shall cease and terminate except the right to receive the applicable Special Liquidation Price as provided herein, and such shares of Existing Preferred Stock shall

no longer be deemed to be outstanding, whether or not the certificates representing such shares of Existing Preferred Stock have been received by the Corporation; provided, however, that, if the Corporation defaults in the payment of the Special Liquidation Price with respect to any Existing Preferred Stock, the rights of the holder(s) thereof with respect to such shares of Existing Preferred Stock shall continue until the Corporation cures such default.

(v) Anything contained herein to the contrary notwithstanding, all or any of the provisions of this Section A.4(h) may be waived by the Existing Senior Majority, by delivery of written notice of waiver to the Corporation prior to the closing of any Event of Sale.

(vi) Any notice required to be given to the holders of shares of Preferred Stock pursuant to Section A.7(g) hereof in connection with an Event of Sale shall include a statement by the Corporation of (A) the Special Liquidation Price which each Preferred Stockholder shall be entitled to receive upon the occurrence of a Special Liquidation under this Section A.4(h) and (B) the extent to which the Corporation will, if at all, be legally prohibited from paying each holder of Preferred Stock the Special Liquidation Price.

(vii) For purposes of this Section A.4(h), an “Event of Sale” shall mean: (A) the sale by the stockholders of voting control of the Corporation, (B) the merger, consolidation or reorganization with or into any other corporation, entity or person or any other corporate reorganization, in which (I) the capital stock of the Corporation immediately prior to such merger, consolidation or reorganization represents less than 50% of the voting power of the surviving entity (or, if the surviving entity is a wholly owned subsidiary, its parent) immediately after such merger, consolidation or reorganization or (II) the surviving entity (or, if the surviving entity is a wholly owned subsidiary, its parent) has a class of securities that is (or has been within 90 days prior to such transaction) tradeable on any public market or exchange or (C) the sale, exclusive license or other disposition of all or substantially all of the assets or intellectual property of the Corporation in a single transaction or series of related transactions. Notwithstanding the foregoing or anything else expressed or implied herein, the transactions contemplated by the Merger Agreement shall not be an “Event of Sale” for purposes of this Certificate.

5. Redemption.

(a) At the request of the Existing Senior Majority (the “Requesting Holders”) made at any time on or after December 15, 2011, the Corporation shall redeem on the Redemption Date, unless otherwise prevented by law, at a redemption price per share equal to the Series C Original Purchase Price for each share of Series C Stock and Series B Original Purchase Price for each share of Series B Stock, plus in each case an amount equal to any declared or accrued but unpaid dividends thereon, all of the Existing Senior Preferred Stock outstanding at the time that such request is made. The total sum payable per share of Existing Senior Preferred Stock on the Redemption Date is hereinafter referred to as the “Redemption Price,” and the payment to be made on the Redemption Date is hereinafter referred to as the “Redemption Payment.” Notwithstanding any limitations specified in this Section A.5, in the event that the Corporation at any time breaches any of the provisions in the this Certificate or any of its representations, warranties, covenants and/or agreements set forth in (i) that certain Stockholders’ Agreement among the Corporation and the parties set forth therein (as amended, the “Stockholders’ Agreement”) or that certain Series C Convertible Redeemable Preferred Stock Purchase Agreement among the Corporation and the signatories thereto (the “Stock Purchase Agreement”), each as entered into contemporaneously with the filing of the Prior Certificate, or (ii) that certain Series B Convertible Redeemable Preferred Stock Purchase Agreement dated as of November 14, 2003 among the Corporation and the signatories thereto (as amended, the “Series B Stock Purchase Agreement”), then upon any such breach the Senior Majority may elect, at their sole discretion, if any such breach is not cured by the 60th day after receipt by the Corporation of notice of such breach from a holder, to accelerate the maturity of

the rights of all of the holders under this Section A.5(a) and cause the immediate redemption of all of the shares of Existing Senior Preferred Stock held by them (less any shares that the Corporation is prevented by law from redeeming, which shall be redeemed by the Corporation as soon as permitted under law). With respect to a breach of which the Corporation is aware or reasonably should be aware, such 60 day period within which the Corporation shall have the right to cure such breach shall be deemed to have commenced on the tenth day after the occurrence of such breach, irrespective of notice of such breach from any holder, if the Corporation shall not have notified the holders of such breach by such date.

(b) On and after the Redemption Date, all rights of any Requesting Holder with respect to those shares of Existing Senior Preferred Stock being redeemed by the Corporation pursuant to Section A.5(a), except the right to receive the applicable Redemption Price per share, shall cease and terminate, and such shares of Existing Senior Preferred Stock shall no longer be deemed to be outstanding, whether or not the certificates representing such shares have been received by the Corporation; provided, however, that, notwithstanding anything to the contrary set forth herein, (A) if the Corporation defaults in the payment of the Redemption Payment, the rights of the Requesting Holder with respect to its shares of Existing Senior Preferred Stock shall continue until the Corporation cures such default, and (B) without limiting any other rights of a Requesting Holder, upon the occurrence of a subsequent Liquidation, with respect to the shares of Existing Senior Preferred Stock in respect of which no Redemption Payment has been received by a Requesting Holder, such Requesting Holder shall be accorded the rights and benefits set forth in Section A.4 hereof in respect of such remaining shares, as if no prior redemption request had been made.

(c) If the Requesting Holders elect to exercise redemption rights hereunder, such Requesting Holders shall send notice of such election (the “Redemption Notice”) by first-class, certified mail, return receipt requested, postage prepaid, to the Corporation at its principal place of business or to any transfer agent of the Corporation. Within five (5) Business Days after receipt of the Redemption Notice, the Corporation shall notify in writing all other Existing Senior Preferred Stockholders of the request by a Requesting Holder for the redemption of Existing Senior Preferred Stock (the “Corporation Notice”). On the twentieth (20th) Business Day following the date upon which the Corporation received the Redemption Notice, the Corporation shall pay each holder of Existing Senior Preferred Stock the applicable Redemption Price pursuant to the terms of Section A.5(a), provided that the Corporation or its transfer agent has received the certificate(s) representing the shares of Existing Senior Preferred Stock to be redeemed. Such payment date shall be referred to herein as the “Redemption Date.” If, on the Redemption Date, less than all the shares of Existing Senior Preferred Stock may be legally redeemed by the Corporation, the redemption of Existing Senior Preferred Stock shall be pro rata according to the respective amounts which would be payable to the Existing Senior Preferred Stockholders in respect of their shares of Existing Senior Preferred Stock if the Redemption Price were paid in full for all such shares, and any shares of Existing Senior Preferred Stock not redeemed shall be redeemed on the first date following such Redemption Date on which the Corporation may lawfully redeem such shares (pro rata according to the respective amounts which would be payable to the Existing Senior Preferred Stockholders in respect of the remaining shares of Existing Senior Preferred Stock if the Redemption Price were paid in full for all such shares). The Corporation shall redeem (to the extent permitted by law) the shares of Existing Senior Preferred Stock on the Redemption Date and the Corporation shall promptly advise each holder of Existing Senior Preferred Stock of the Redemption Date or of the relevant facts applicable thereto preventing such redemption. Upon redemption of only a portion of the number of shares covered by a Existing Senior Preferred Stock certificate, the Corporation shall issue and deliver to or upon the written order of the holder of such Existing Senior Preferred Stock certificate, at the expense of the Corporation, a new certificate covering the number of shares of the Existing Senior Preferred Stock representing the unredeemed portion of the Existing Senior Preferred Stock certificate, which new certificate shall entitle the holder thereof to all the rights, powers and privileges of a holder of such shares.

(d) Shares of the Existing Senior Preferred Stock are not subject to or entitled to the benefit of any sinking fund.

6. Voting.

(a) Subject to any separate voting rights provided for herein or otherwise required by law, for so long as Existing Senior Preferred Stock remains outstanding, the holders of Existing Preferred Stock shall be entitled to vote, together with the holders of Common Stock as one class, on all matters as to which holders of Common Stock shall be entitled to vote, in the same manner and with the same effect as such holders of Common Stock. In any such vote, each share of Existing Preferred Stock shall entitle the holder thereof to the number of votes per share that equals the number of shares of Common Stock (including fractional shares) into which each such share of Preferred Stock is then convertible, rounded up to the nearest one-tenth of a share, but not including any shares of Common Stock issuable upon conversion of any dividends accrued on such Existing Preferred Stock.

(b) In addition to the rights specified in Section A.6(a), for so long as any shares of Existing Senior Preferred Stock are outstanding, the holders of the Existing Senior Preferred Stock, voting as a separate class, shall have the right to elect six (6) members of the Board of Directors of the Corporation (such directors, the “Existing Preferred Directors”). In any election of Existing Preferred Directors pursuant to this Section A.6(b), each holder of Existing Senior Preferred Stock shall be entitled to one vote for each share of Common Stock (including fractional shares) into which each such share of Existing Senior Preferred Stock is then convertible, rounded up to the nearest one-tenth of a share (determined as set forth in the second sentence of Section A.6(a) hereof), and no holder of Existing Senior Preferred Stock shall be entitled to cumulate its votes by giving one candidate more than one vote per share. The voting right of the holders of Existing Senior Preferred Stock, contained in this Section A.6(b), may be exercised at a special meeting of the holders of Existing Senior Preferred Stock called as provided in accordance with the by-laws of the Corporation, at any annual or special meeting of the stockholders of the Corporation, or by written consent of such holders of Existing Senior Preferred Stock in lieu of a meeting. The Existing Preferred Directors elected pursuant to this Section A.6(b) shall serve from the date of their election and qualification until their successors have been duly elected and qualified.

(c) A vacancy in the directorships elected by the holders of Existing Senior Preferred Stock pursuant to Section A.6(b), may be filled by a vote at a meeting called in accordance with the by-laws of the Corporation or written consent in lieu of such meeting of the holders of such Existing Senior Preferred Stock.

(d) For so long as Existing Preferred Stock remains outstanding, the holders of capital stock of the Corporation, voting as a single class, shall elect the remaining member or members of the Board of Directors of the Corporation. In any election of directors pursuant to this Section A.6(d), each stockholder shall be entitled to one vote for each share of Common Stock held or, if Existing Preferred Stock, into which each such share of Existing Preferred Stock is then convertible (determined in accordance with Section A.6(a) hereof), and no stockholder shall be entitled to cumulate its votes by giving one candidate more than one vote per share. The voting right of the stockholders contained in this Section A.6(d) apply only so long as shares of Existing Preferred Stock remains and outstanding and may be exercised at a special meeting of the stockholders called as provided in accordance with the by-laws of the Corporation, at any annual or special meeting of the stockholders of the Corporation, or by written consent of the stockholder in lieu of a meeting. The director or directors elected pursuant to this Section A.6(d) shall serve from the date of their election and qualification until their successors have been duly elected and qualified.

(e) A vacancy in the directorship or directorships elected by the stockholders pursuant to Section A.6(d), may be filled by a vote at a meeting called in accordance with the by-laws of the Corporation or written consent in lieu of such meeting of the stockholders of the Corporation.

(f) For so long as shares of Existing Preferred Stock are outstanding, the Corporation shall not, directly or indirectly, through a merger, consolidation, reorganization or otherwise, without the affirmative approval of the Existing Senior Majority, acting separately from the holders of Common Stock or any other securities of the Corporation, given by written consent in lieu of a meeting or by vote at a meeting called for such purpose, for which meeting or approval by written consent timely and specific notice in the manner provided in the by-laws of the Corporation (“Notice”) shall have been given to each holder of such Existing Senior Preferred Stock, do the following:

(xv) except as otherwise required by this Certificate or as contemplated in the Series A-1 Purchase Agreement, increase or decrease the authorized number of the members of the Board of Directors;

The foregoing approval shall be obtained in addition to any approval required by law.

(g) The Corporation shall obtain the consent of the Board of Directors before it may authorize or issue any additional shares of capital stock of the Corporation, other than the issuance of any shares of New Preferred Stock as contemplated by this Certificate or the Series A-1 Purchase Agreement, or any of its subsidiaries.

7. Conversion.

(a) Any Existing Preferred Stockholder shall have the right, at any time or from time to time, to convert any or all of its shares of Existing Preferred Stock into that number of fully paid and nonassessable shares of Common Stock for each share of Existing Preferred Stock so converted equal to the quotient of the Series A Original Purchase Price, Series B Original Purchase Price or Series C Original Purchase Price, as applicable, for such share divided by the Series A Conversion Price, the Series B Conversion Price or the Series C Conversion Price (each as defined in Section A.7(e) hereof), as applicable, for such share of Existing Preferred Stock, as last adjusted and then in effect, rounded up to the nearest one-tenth of a share; provided, however, that cash shall be paid in lieu of the issuance of fractional shares of Common Stock, as provided in Section A.7(d) hereof.

(b) (i) Any Existing Preferred Stockholder who exercises the right to convert shares of Existing Preferred Stock into shares of Common Stock, pursuant to this Section A.7 shall be entitled to payment of all accrued dividends, whether or not declared and all declared but unpaid dividends payable with respect to such Existing Preferred Stock pursuant to Section A.3 herein, up to and including the Conversion Date (as defined in Section A.7(b)(iii) hereof).

(ii) Any Existing Preferred Stockholder may exercise the right to convert such shares into Common Stock pursuant to this Section A.7 by delivering to the Corporation during regular business hours, at the office of the Corporation or any transfer agent of the Corporation or at such other place as may be designated by the Corporation, the certificate or certificates for the shares to be converted (the “Existing Preferred Certificate”), duly endorsed or assigned in blank to the Corporation (if required by it) or an affidavit of loss as to the same.

(iii) Each Existing Preferred Certificate shall be accompanied by written notice stating that such holder elects to convert such shares and stating the name or names (with address) in which the certificate or certificates for the shares of Common Stock (the “Common Certificate”) are to be issued. Such conversion shall be deemed to have been effected on the date when such delivery is made, and such date is referred to herein as the “Conversion Date.”

(iv) As promptly as practicable thereafter, the Corporation shall issue and deliver to or upon the written order of such holder, at the place designated by such holder, (A) a Common Certificate for the number of full shares of Common Stock to which such holder is entitled and (B) a check or cash in respect of any fractional interest in shares of Common Stock to which such holder is entitled, as provided in Section A.7(d) hereof, payable with respect to the shares so converted up to and including the Conversion Date.

(v) The person in whose name the Common Certificate or Certificates are to be issued shall be deemed to have become a holder of record of Common Stock on the applicable Conversion Date, unless the transfer books of the Corporation are closed on such Conversion Date, in which event the holder shall be deemed to have become the stockholder of record on the next succeeding date on which the transfer books are open, provided that the Series A Conversion Price, Series B Conversion Price or Series C Conversion Price, as applicable, upon which the conversion shall be executed shall be that in effect on the Conversion Date.

(vi) Upon conversion of only a portion of the number of shares covered by an Existing Preferred Certificate, the Corporation shall issue and deliver to or upon the written order of the holder of such Existing Preferred Certificate, at the expense of the Corporation, a new certificate covering the number of shares of Existing Preferred Stock representing the unconverted portion of the Existing Preferred Certificate, which new certificate shall entitle the holder thereof to all the rights, powers and privileges of a holder of such Existing Preferred Stock.

(c) If an Existing Preferred Stockholder shall surrender more than one share of the same class of Existing Preferred Stock for conversion at any one time, then the number of full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Existing Preferred Stock so surrendered.

(d) No fractional shares of Common Stock shall be issued upon conversion of Existing Preferred Stock. The Corporation shall instead pay a cash adjustment for any such fractional interest in an amount equal to the Current Market Price thereof on the Conversion Date, as determined in accordance with Section A.7(e)(vii) hereof.

(e) For all purposes of this Article III, Part A, the initial conversion price of the Series A Stock shall be the Series A Original Purchase Price, the initial conversion price of the Series B Stock shall be the Series B Original Purchase Price and the initial conversion price of the Series C Stock shall be the Series C Original Purchase Price, in each case subject to adjustment from time to time as follows (the conversion price of any or each of the Series A Stock, Series B Stock and the Series C Stock, as adjusted from time to time, is sometimes referred to generically in this Section A.7 as the “Conversion Price”):

(i) Subject to Section A.7(e)(ii) and A.7(e)(x) below, if the Corporation shall, at any time or from time to time after the Effective Time, issue or sell any shares of Common Stock (which term, for purposes of this Section A.7(e)(i), including all subsections thereof, shall be deemed to include all other securities convertible into, or exchangeable or exercisable for, shares of Common Stock (including, but not limited to, Existing Preferred Stock) or options to purchase or other rights to subscribe for such convertible or exchangeable securities, in each case other than Excluded Stock (as defined in Section A.7(e)(ii) below), for a consideration per share less than the Series C Conversion Price in effect immediately prior to the issuance of such Common Stock or other securities (a “Dilutive Issuance”), then (X) the Conversion Price for the Series A Stock (the “Series A Conversion Price”) in effect immediately prior to each such Dilutive Issuance shall automatically be reduced to a price equal to the product obtained by multiplying such Series A Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Existing Preferred Stock, upon exercise of outstanding stock options and warrants or otherwise under Section A.7(e)(i)(d)) plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for the additional stock so issued would purchase at such Series C Conversion Price as in effect immediately prior to such issuance, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Existing Preferred Stock, upon exercise of outstanding stock options or otherwise under Section A.7(e)(i)(d)) plus the number of shares of additional stock so issued, (Y) the Conversion Price for the Series B Stock (the “Series B Conversion Price”) in effect immediately prior to each such Dilutive Issuance shall automatically be reduced to a price equal to the product obtained by multiplying such Series B Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Existing Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Existing Preferred Stock) plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for the additional stock so issued would purchase at such Series C Conversion Price as in effect immediately prior to such issuance, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Existing Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of

additional stock so issued, and (Z) the Conversion Price for the Series C Stock (the “Series C Conversion Price”) in effect immediately prior to each such Dilutive Issuance shall automatically be reduced to a price equal to the product obtained by multiplying such Series C Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Existing Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Existing Preferred Stock) plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for the additional stock so issued would purchase at such Series C Conversion Price as in effect immediately prior to such issuance, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Existing Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Existing Preferred Stock) plus the number of shares of additional stock so issued. For purposes of this Section A.7(e)(i), the number of shares of Common Stock deemed issuable upon conversion of such outstanding shares of Existing Preferred Stock shall be determined without giving effect to any adjustments to the applicable Conversion Price resulting from the Dilutive Issuance that is the subject of this calculation. For the purposes of any adjustment of the Conversion Price pursuant to this Section A.7(e)(i), the following provisions shall be applicable.

a. In the case of the issuance of Common Stock in whole or in part for cash, the consideration shall be deemed to be the amount of cash paid therefor after deducting therefrom any discounts, commissions or other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with the issuance and sale thereof, plus the value of any property other than cash received by the Corporation, determined as provided in Section A.7(e)(i)(b) hereof, plus the value of any other consideration received by the Corporation determined as set forth in Section A.7(e)(i)(c) hereof.

b. In the case of the issuance of Common Stock for a consideration in whole or in part in property other than cash, the value of such property other than cash shall be deemed to be the fair market value of such property as determined in good faith by the Board of Directors, irrespective of any accounting treatment; provided, however, that such fair market value of such property as determined by the Board of Directors shall not exceed the aggregate Current Market Price (as defined in Section A.7(e)(viii) hereof) of the shares of Common Stock or such other securities being issued, less any cash consideration paid for such shares, determined as provided in Section A.7(e)(i)(a) hereof and less any other consideration received by the Corporation for such shares, determined as set forth in Section A.7(e)(i)(c) hereof.

c. In the case of the issuance of Common Stock for consideration in whole or in part other than cash or property, the value of such other consideration shall be deemed to be the aggregate par value of such Common Stock (or the aggregate stated value if such Common Stock has no par value).

d. In the case of the issuance of options or other rights to purchase or subscribe for Common Stock or the issuance of securities by their terms convertible into or exchangeable or exercisable for Common Stock or options to purchase or other rights to subscribe for such convertible or exchangeable or exercisable securities:

and (c) hereof), if any, received by the Corporation upon the issuance of such options or rights plus the minimum purchase price provided in such options or rights for the Common Stock covered thereby (the consideration in each case to be determined in the manner provided in Sections A.7(e)(i)(a), (b) and (c) hereof);

ii. the aggregate maximum number of shares of Common Stock deliverable upon conversion of, or in exchange for, any such convertible or exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration received by the Corporation for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the minimum additional consideration, if any, to be received by the Corporation upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in Sections A.7(e)(i)(a), (b) and (c) hereof);

iii. if there is any change (whether automatic pursuant to the terms contained therein or as a result of the amendment of such terms) in the exercise price of, or number of shares deliverable upon exercise of, any such options or rights or upon the conversion or exchange of any such convertible or exchangeable securities (other than a change resulting from the original antidilution provisions thereof in place at the time of issuance of such security), then the applicable Conversion Price shall automatically be readjusted in proportion to such change (notwithstanding the foregoing, no adjustment pursuant to this clause shall have the effect of increasing the applicable Conversion Price to an amount which exceeds the lower of (i) the applicable Conversion Price on the original adjustment date, or (ii) the applicable Conversion Price that would have resulted from any Dilutive Issuances between the original adjustment date and such readjustment date);

iv. upon the expiration of any such options or rights or the termination of any such rights to convert or exchange such convertible or exchangeable securities (or in the event that the change that precipitated an adjustment pursuant to Section A.7(e)(i)(d)(iii) hereof is reversed or terminated, or expires), then the applicable Conversion Price shall be automatically readjusted to the applicable Conversion Price that would have been obtained had such options, rights or convertible or exchangeable securities not been issued; and

v. if the terms of any option or convertible security (excluding options or convertible securities which, upon exercise, conversion or exchange thereof, would entitle the holder thereof to receive shares of Common Stock which are Excluded Stock), the issuance of which was not a Dilutive Issuance, are revised after the Original Issuance Date (either automatically pursuant the provisions contained therein or as a result of an amendment to such terms) to provide for either (1) any increase in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any such option or convertible security or (2) any decrease in the consideration payable to the Corporation upon such exercise, conversion or exchange, then such option or convertible security, as so amended, and the shares of Common Stock subject thereto shall be deemed to have been issued effective upon such increase or decrease becoming effective.

(ii) “Excluded Stock” shall mean:

a. Common Stock issued upon conversion of any shares of Existing Preferred Stock, including any shares of Common Stock issuable upon conversion of any dividends accrued on such Existing Preferred Stock;

b. Common Stock issued or issuable to officers, directors or employees of or consultants or independent contractors to the Corporation, pursuant to any written agreement, plan or arrangement to purchase, or rights to subscribe for, such Common Stock, including Common Stock issued under the Corporation’s 2003 Long-Term Incentive Plan, as amended, or other equity incentive plan or other agreements that have been approved in form and in substance by the Existing Senior Majority, calculated in accordance with Section A.6(a) of Article III herein (including, in such calculation, any outstanding restricted stock awards held by such holders), and which, as a condition precedent to the issuance of such shares, provide for the vesting of such shares and subject such shares to restrictions on transfer and rights of first offer in favor of the Corporation, and restricted stock grants to directors, employees or consultants as approved by the Board of Directors of the Corporation; provided, however, that the maximum number of shares of Common Stock heretofore or hereafter issuable pursuant to the Corporation’s 2003 Long-Term Incentive Plan, as amended, and all such agreements, plans and arrangements shall not exceed 2,015,666 shares of Common Stock;

c. Common Stock issued as a stock dividend or distribution on the Existing Preferred Stock payable in shares of Common Stock, or capital stock of any other class issuable upon any subdivision, recombination, split-up or reverse stock split of all the outstanding shares of such class of capital stock;

d. Common Stock or other securities issued or issuable to banks, lenders or landlords, provided that each such issuance is approved by the Board of Directors, including, but not limited to, warrants to acquire Common Stock held by Silicon Valley Bank (or its affiliates, successors and assignees), warrants to purchase Preferred Stock issued or to be issued to GE Healthcare Financial Services, Inc. (“GEHFS”) and Oxford Finance Corporation (“OFC”) pursuant to a proposed debt financing approved by the Board of Directors (the “GE Financing”), shares of Preferred Stock issued or issuable to GE in connection with the GE Financing or upon exercise by GEHFS or OFC of warrants issued in the GE Financing and shares of common stock issuable upon conversion of any such shares of Preferred Stock issued to GEHFS or OFC pursuant to the GE Financing;

e. Common Stock or other securities issued or issuable to third parties in connection with strategic partnerships or alliances, corporate partnerships, joint ventures or other licensing transactions, provided that each such transaction and related issuance is approved by the Board of Directors, including, but not limited to, (A) any shares of Preferred Stock or Common Stock issued or issuable to Ipsen Pharma SAS (“Ipsen”), pursuant to the terms of that certain License Agreement, as amended and may be amended with the approval of the Board of Directors of the Corporation and in effect from time to time, by and between the Corporation and Ipsen as payment milestones in lieu of cash payments and (B) hares of Series A-5 Stock issued or issuable pursuant to that certain Stock Issuance Agreement as of March 29, 2011 by and between the Corporation and Nordic Bioscience and the letter agreement as of March 29, 2011 by and between the Corporation and Nordic Bioscience, pursuant to which the Corporation will issue shares of the Corporation’s Series A-5 Convertible Preferred Stock, $0.01 par value per share and the issuance of Series A-6 Stock issued or to be issued as dividends on such Series A-5 Stock, and shares of Common Stock issuable upon conversion of any such shares of Series A-5 Stock and Series A-6 Stock;

f. Common Stock or other securities issued or issuable pursuant to the acquisition by the Corporation of any other corporation, partnership, joint venture, trust or other entity by any merger, stock acquisition, reorganization, or purchase of substantially all assets or otherwise in which the Corporation or its stockholders of record immediately prior to the effective date of such transaction, directly or indirectly, own at least a majority of the voting power of the acquired entity or the resulting entity after such transaction, in each case so long as approved by the Board of Directors;

g. Common Stock or other securities, the issuance of which is approved by the Existing Senior Majority, with such approval expressly waiving the application of the anti-dilution provisions of this Section A.7 as a result of such issuance;

h. Preferred Stock (and Common Stock issuable upon conversion of such Preferred Stock) or Common Stock issued or issuable pursuant to any warrant outstanding as of the date hereof or any warrant and any shares of Preferred Stock or common stock, or common stock issued upon exercise of any Preferred Stock, issued in connection with the Qualified Financing, including, but not limited to a warrant for shares of Series A-1 Preferred Stock issued or issuable to Leerink Swan, any shares of Preferred Stock or Common Stock upon exercise thereof and any Common Stock issuable upon conversion of such Preferred Stock issued upon exercise thereof;

j. All shares of Preferred Stock issued in connection with the Qualified Financing as provided in this Certificate and the Series A-1 Purchase Agreement, and all shares of Common Stock issued or issuable upon conversion of any such shares of Preferred Stock.

(iii) If the number of shares of Common Stock outstanding at any time after the Effective Time is increased by a stock dividend payable in shares of Common Stock or by a subdivision or split-up of shares of Common Stock, then, following the record date fixed for the determination of holders of Common Stock entitled to receive such stock dividend, subdivision or split-up, the applicable Conversion Price shall be appropriately decreased in the form of a Proportional Adjustment (as defined in Section A.8) so that the number of shares of Common Stock issuable on conversion of each share of Existing Preferred Stock shall be increased in proportion to such increase in outstanding shares.

(iv) If the number of shares of Common Stock outstanding at any time after the Effective Time is decreased by a combination of the outstanding shares of Common Stock (other than pursuant to the Reverse Split), then, following the record date for such combination, the applicable Conversion Price shall be appropriately increased in the form of a Proportional Adjustment so that the number of shares of Common Stock issuable on conversion of each share of Existing Preferred Stock shall be decreased in proportion to such decrease in outstanding shares.

(v) Except as contemplated in Certificate and the Series A-1 Purchaser Agreement, if at any time after the Effective Time, the Corporation shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Corporation (other than shares of Common Stock) or in cash or other property, then and in each such event provision shall be made so that the holders of the Existing Preferred Stock shall receive upon conversion thereof in addition to the number of shares of Common Stock receivable thereupon, the kind and amount of securities of the Corporation, cash or other property which they would have been entitled to receive had the Existing Preferred Stock been converted into Common Stock on the date of such event and had they thereafter, during the period from the date of such event to and including the conversion date, retained such securities receivable by them as aforesaid during such period, giving application to all adjustments called for during such period under this paragraph with respect to the rights of the holders of the Existing Preferred Stock; and provided further, however, that no such adjustment shall be made if the holders of Existing Preferred Stock simultaneously receive a dividend or other distribution of such securities, cash, or other property in an amount equal to the amount of such securities, cash, or other property as they would have received if all outstanding shares of Existing Preferred Stock had been converted into Common Stock on the date of such event.

(vi) Subject to the provisions of Section A.4(h) above, in the event, at any time after the Effective Time, of any capital reorganization, or any reclassification of the capital stock of the

Corporation (other than pursuant to the Reverse Split, other than as contemplated under this Certificate and the Series A-1 Purchase Agreement and other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), or the consolidation or merger of the Corporation with or into another person (other than pursuant to the Merger Agreement and other than any consolidation or merger in which the Corporation is the continuing corporation and which does not result in any change in the powers, designations, preferences and rights, or the qualifications, limitations or restrictions, if any, of the capital stock of the Corporation) or of the sale or other disposition of all or substantially all the properties and assets of the Corporation in their entirety to any other person (any such transaction, an “Extraordinary Transaction”), then the Corporation shall provide appropriate adjustment in the form of a Proportional Adjustment to the applicable Conversion Price with respect to each share of Existing Preferred Stock outstanding after the effectiveness of such Extraordinary Transaction (excluding any Existing Preferred Stock redeemed pursuant to Section A.5 hereof in connection therewith) such that each share of Existing Preferred Stock outstanding immediately prior to the effectiveness of the Extraordinary Transaction (other than shares redeemed pursuant to Section A.5 hereof) shall be convertible into the kind and number of shares of stock or other securities or property of the Corporation, or of the corporation resulting from or surviving such Extraordinary Transaction, that a holder of the number of shares of Common Stock deliverable (immediately prior to the effectiveness of the Extraordinary Transaction) upon conversion of such share of Existing Preferred Stock would have been entitled to receive upon such Extraordinary Transaction. The provisions of this Section A.7(e)(v) shall similarly apply to successive Extraordinary Transactions.

(vii) All calculations under this Section A.7(e) shall be made to the nearest one-tenth of a cent ($.001) or to the nearest one-tenth of a share, as the case may be.

(viii) For the purpose of any computation pursuant to Section A.7(d) hereof or this Section A.7(e), the Current Market Price at any date of one share of Common Stock shall be defined as the average of the daily closing prices for the 30 consecutive Business Days ending on the fifth (5th) Business Day before the day in question (as adjusted for any stock dividend, split-up, combination or reclassification that took effect during such 30 Business Day period), determined as follows:

a. If the Common Stock is listed or admitted for trading on a national securities exchange, then the closing price for each day shall be the last reported sales price regular way or, in case no such reported sales took place on such day, the average of the last reported bid and asked prices regular way, in either case on the principal national securities exchange on which the Common Stock is listed or admitted to trading.

b. If the Common Stock is not at the time listed or admitted for trading on any such exchange, then such price shall be equal to the last reported bid and asked prices on such day as reported by the NASD OTCBB or the National Quotation Bureau, Inc., or any similar reputable quotation and reporting service if such quotation is not reported by the NASD OTCBB or the National Quotation Bureau, Inc.

c. If the Common Stock is not traded in such manner that the quotations referred to in this Section A.7(d)(viii) are available for the period required hereunder, then the Current Market Price shall be the fair market value of such share, as determined in good faith by a majority of the entire Board of Directors.

(ix) In any case in which the provisions of this Section A.7(e) shall require that an adjustment shall become effective immediately after a record date for an event, the Corporation may defer until the occurrence of such event (A) issuing to the holder of any shares of Existing Preferred Stock

converted after such record date and before the occurrence of such event the additional shares of capital stock issuable upon such conversion by reason of the adjustment required by such event over and above the shares of capital stock issuable upon such conversion before giving effect to such adjustment, and (B) paying to such holder any cash amounts in lieu of fractional shares pursuant to Section A.7(d) hereof; provided, however, that the Corporation shall deliver to such holder a due xxxx or other appropriate instrument evidencing such holder’s right to receive such additional shares and such cash upon the occurrence of the event requiring such adjustment.

(x) If a state of facts shall occur that, without being specifically controlled by the provisions of this Section A.7, would not fairly protect the conversion rights of the holders of the Existing Preferred Stock in accordance with the essential intent and principles of such provisions, then the Board of Directors shall make an adjustment in the application of such provisions, in accordance with such essential intent and principles, so as to protect such conversion rights.

(xi) Notwithstanding the foregoing, there shall be no adjustment to the Conversion Price for any issuance or deemed issuance of any shares of Common Stock (which term, for purposes of this Section A.7(e)(x), including all subsections thereof, shall be deemed to include all securities convertible into, or exchangeable or exercisable for, whether directly or indirectly, shares of Common Stock) for a consideration per share greater than the Series C Original Purchase Price.

(f) Whenever the applicable Conversion Price shall be adjusted as provided in Section A.7(e) hereof, the Corporation shall forthwith file and keep on record at the office of the Secretary of the Corporation and at the office of its transfer agent or at such other place as may be designated by the Corporation, a statement, signed by both its President or Chief Executive Officer and its Treasurer or Chief Financial Officer, showing in detail the facts requiring such adjustment and the applicable Conversion Price that shall be in effect after such adjustment. The Corporation shall also cause a copy of such statement to be sent by first-class, certified mail, return receipt requested, postage prepaid, to each Existing Preferred Stockholder at such holder’s address appearing on the Corporation’s records. Where appropriate, such copy shall be given in advance of any such adjustment and shall be included as part of a notice required to be mailed under the provisions of Section A.7(g) hereof.

(g) In the event the Corporation shall propose to take any action of the types described in Section A.7(e)(i), (iii), (iv) or (v) hereof, or any other Event of Sale, the Corporation shall give notice to each Existing Preferred Stockholder in the manner set forth in Section A.7(f) hereof, which notice shall specify the record date, if any, with respect to any such action and the date on which such action is to take place. Such notice shall also set forth such facts with respect thereto as shall be reasonably necessary to indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the applicable Conversion Price with respect to the Existing Preferred Stock, and the number, kind or class of shares or other securities or property which shall be deliverable or purchasable upon each conversion of Preferred Stock. In the case of any action that would require the fixing of a record date, such notice shall be given at least 20 days prior to the record date so fixed, and in the case of any other action, such notice shall be given at least 30 days prior to the taking of such proposed action.

(h) The Corporation shall pay all documentary, stamp or other transactional taxes attributable to the issuance or delivery of shares of capital stock of the Corporation upon conversion of any shares of Existing Preferred Stock; provided, however, that the Corporation shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificate for such shares in a name other than that of the Existing Preferred Stockholder in respect of which such shares of Existing Preferred Stock are being issued.

(i) The Corporation shall reserve out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the Existing Preferred Stock, sufficient shares of Common Stock to provide for the conversion of all outstanding shares of Existing Preferred Stock.

(j) All shares of Common Stock which may be issued in connection with the conversion provisions set forth herein will, upon issuance by the Corporation, be validly issued, fully paid and nonassessable, not subject to any preemptive or similar rights, and free from all taxes, liens or charges with respect thereto created or imposed by the Corporation.

(k) Upon the consummation of a qualified firm commitment underwritten public offering of Common Stock of the Corporation registered under the Securities Act of 1933, as amended, pursuant to which (i) the Company valuation prior to the offering is equal to or greater than $200 million and (ii) the aggregate gross proceeds to the Corporation (before deduction of underwriters commissions and expenses) are at least $40 million (a “Qualified Public Offering”), each share of Existing Preferred Stock then outstanding shall, by virtue of and immediately prior to the closing of such qualified firm commitment public offering and without any action on the part of the holder thereof, be deemed automatically converted into that number of shares of Common Stock of which the Existing Preferred Stock would be convertible if such conversion were to occur immediately prior to closing of the Qualified Public Offering. The holder of any shares of Existing Preferred Stock converted into Common Stock pursuant to this Section A.7(k) shall be entitled to payment of all declared or accrued but unpaid dividends, if any, payable on or with respect to such shares up to and including the date of the closing of such Qualified Public Offering which shall be deemed the Conversion Date for purposes of this Section A.7(k).

Notwithstanding the foregoing, the Reverse Split shall not rigger or give rise to any Proportional Adjustment.

9. Forced Conversion in the Qualified Financing.

(h) In the event of any Liquidation, after payments shall have been made first to the New Preferred Stockholders and to the holders of any class or series of capital stock that is senior to or on parity with the New Preferred Stock, or any series thereof, as in effect from time to time, and to the holders of class or series of capital stock that is junior to or on parity with the New Preferred Stock but senior to the Common Stock, of the full amount to which they each shall be entitled as aforesaid, the holders of Common Stock, as a class, shall be entitled to share ratably with the holders of Participating Preferred Stock as provided in the last sentence in this Section B.4(h)) in all remaining assets of the Corporation legally available for distribution to its stockholders. For purposes of calculating the amount of any payment to be paid upon any such Liquidation pursuant to the participation feature described in this Section B.4(h), each share of such Participating Preferred Stock shall be deemed to be that number of shares (including fractional shares and any shares attributable to the payment of accrued and unpaid dividends upon conversion of such Participating Preferred Stock pursuant to Section B.7(b)) of Common Stock into which it is then convertible, rounded to the nearest one-tenth of a share.

(i) (i) In the event of and simultaneously with the closing of an Event of Sale, the Corporation shall, unless waived by the New Senior Majority or otherwise prevented by law, redeem all of the shares of New Preferred Stock then outstanding for a cash amount per share determined as set forth in Sections B.4(a) through (h) hereof (the “Special Liquidation Price,” said redemption being referred to herein as a “Special Liquidation”). In the event the Event of Sale involves consideration that does not consist of cash, then the Special Liquidation Price may be paid with such consideration having a value equal to the Special Liquidation Price. To the extent there is any cash consideration in connection with an Event of Sale, at the option of the New Senior Majority, the cash consideration will first (i) be applied to satisfy the Special Liquidation Price payable to the Series A-1 Stockholders and to the holders of any other class or series of capital stock that is senior to or on parity with the Series A-1 Stock as to Liquidation; and then (ii) be applied to satisfy the Special Liquidation Price payable to the holders of Series A-2 Stock and to the holders of any other class or series of capital stock that is junior to the Series A-1 Stock but senior to or on parity with the Series A-2 Stock as to Liquidation; and then (iii) be applied to satisfy the Special Liquidation Price payable to holders of Series A-3 Stock, Series A-5 Stock, Series A-6 Stock and any other class or series of capital stock that is junior to the Series A-2 Stock but senior to or on parity with the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock as to Liquidation (in relative proportion to the full liquidation preference the Series A-3 Stockholders, Series A-5 Stockholders, Series A-6 Stockholders and

the holders of such other class or series of capital stock would have received had there been sufficient cash consideration to have paid their liquidation preference in full) and then (iv) be applied to satisfy the Special Liquidation Price payable to the holders of Series A-4 Stock and to the holders of any other class or series of capital stock that is junior to the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock but senior to or on parity with the Series A-4 Stock, in all cases, prior to the payment thereof to any other stockholders of the Corporation. For all purposes of this Section B.4(i), the Special Liquidation Price shall be equal to that amount per share which would be received by each New Preferred Stockholder if, in connection with an Event of Sale, all the consideration paid in exchange for the assets or the shares of capital stock (as the case may be) of the Corporation were actually paid to and received by the Corporation and the Corporation were immediately thereafter liquidated and its assets distributed pursuant to Sections B.4(a) through (h) hereof. To the extent that one or more redemptions (as described in Section B.5 hereof) and/or Special Liquidations are occurring concurrently, the Special Liquidation under this Section B.4(i) shall be deemed to occur first. The date upon which the Special Liquidation shall occur is sometimes referred to herein as the “Special Liquidation Date”.

(ii) In the absence of an applicable waiver pursuant to Section B.4(i) above, at any time on or after the Special Liquidation Date, a New Preferred Stockholder shall be entitled to receive the Special Liquidation Price for each such share of New Preferred Stock owned by such holder. Subject to the provisions of Section B.4(i)(iii) hereof, payment of the Special Liquidation Price will be made to each such holder upon actual delivery to the Corporation or its transfer agent of the certificate of such holder representing such shares of New Preferred Stock, as the case may be, or an affidavit of loss as to the same.

(iii) If on the Special Liquidation Date less than all the shares of New Preferred Stock then outstanding may be legally redeemed by the Corporation, the Special Liquidation shall be made first as to the Series A-1 Stock (and any other class or series of capital stock that is senior to or on parity with the Series A-1 Stock as to Liquidation), pro rata with respect to such Series A-1 Stock (or such other class or series of capital stock that is senior to or on parity with the Series A-1 Stock as to Liquidation) based upon the number of outstanding shares of Series A-1 Stock (or such other class or series of capital stock that is senior to or on parity with the Series A-1 Stock as to Liquidation) then owned by each such holder thereof until such holders are satisfied in full, and then to the Series A-2 Stock (and any other class or series of capital stock that is junior to the Series A-1 Stock but senior to or on parity with the Series A-2 Stock as to Liquidation), pro rata with respect to such Series A-2 Stock (or such other class or series of capital stock that is junior to the Series A-1 Stock but senior to or on parity with the Series A-2 Stock as to Liquidation) based upon the number of outstanding shares of Series A-2 Stock (or such other class or series of capital stock that is junior to the Series A-1 Stock but senior to or on parity with the Series A-2 Stock as to Liquidation) then owned by each such holder thereof until such holders are satisfied in full, and then to the holders of the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock (and any other class or series of capital stock that is junior to the Series A-2 Stock but senior to or on parity with the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock as to Liquidation), pro rata with respect to such Series A-3, Stock Series A-5 Stock and Series A-6 Stock (or such other class or series of capital stock that is junior to the Series A-2 Stock but senior to or on parity with the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock as to Liquidation) based upon the number of outstanding shares of Series A-3 Stock, Series A-5 Stock and Series A-6 Stock (or such other class or series of capital stock that is junior to the Series A-2 Stock but senior to or on parity with the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock as to Liquidation) then owned by each holder thereof, and then to the Series A-4 Stock (and any other class or series of capital stock that is junior to the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock but senior to or on parity with the Series A-4 Stock as to Liquidation), pro rata with respect to such Series A-4 Stock (or such other class or series of capital stock that is junior to the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock but senior to or on parity with the Series A-4 Stock as to Liquidation) based upon the number of outstanding shares of Series A-4 Stock (or such other

class or series of capital stock that is junior to the Series A-3 Stock, Series A-5 Stock and Series A-6 Stock but senior to or on parity with the Series A-4 Stock as to Liquidation) then owned by each such holder thereof until such holders are satisfied in full.

(iv) On and after any Special Liquidation Date, all rights in respect of the shares of New Preferred Stock to be redeemed shall cease and terminate except the right to receive the applicable Special Liquidation Price as provided herein, and such shares of New Preferred Stock shall no longer be deemed to be outstanding, whether or not the certificates representing such shares of New Preferred Stock have been received by the Corporation; provided, however, that, if the Corporation defaults in the payment of the Special Liquidation Price with respect to any New Preferred Stock, the rights of the holder(s) thereof with respect to such shares of New Preferred Stock shall continue until the Corporation cures such default.

(v) Anything contained herein to the contrary notwithstanding, all or any of the provisions of this Section B.4(i) may be waived by the New Senior Majority, by delivery of written notice of waiver to the Corporation prior to the closing of any Event of Sale.

(vi) Any notice required to be given to the holders of shares of New Preferred Stock pursuant to Section B.7(g) hereof in connection with an Event of Sale shall include a statement by the Corporation of (A) the Special Liquidation Price which each New Preferred Stockholder shall be entitled to receive upon the occurrence of a Special Liquidation under this Section B.4(i) and (B) the extent to which the Corporation will, if at all, be legally prohibited from paying each holder of New Preferred Stock the Special Liquidation Price.

5. Definition of “Event of Sale” and “Shell Company Successor”. For purposes of this Part B of Article III, an “Event of Sale” shall mean: (A) the sale by the stockholders of voting control of the Corporation, (B) the merger, consolidation or reorganization with or into any other corporation, entity or person or any other corporate reorganization, in which (I) the capital stock of the Corporation immediately prior to such merger, consolidation or reorganization represents less than 50% of the voting power of the surviving entity (or, if the surviving entity is a wholly owned subsidiary, its parent) immediately after such merger, consolidation or reorganization or (II) the surviving entity (or, if the surviving entity is a wholly owned subsidiary, its parent) has a class of securities that is (or has been within 90 days prior to such transaction) tradeable on any public market or exchange or (C) the sale, exclusive license or other disposition of all or substantially all of the assets or intellectual property of the Corporation in a single transaction or series of related transactions. Notwithstanding the foregoing and for purposes of clarification, the term “Event of Sale” shall not include any transaction involving the Corporation and the Shell Company Successor that is described in clause (iii) of the Shell Company Successor definition set forth below. “Shell Company Successor” means a shell company that (i) has securities registered under the Securities Exchange Act of 1934, as amended, (ii) has nominal operations and nominal assets (prior to any of the transactions described in clause (iii)) and (iii) directly or indirectly through one or more direct or indirect subsidiaries acquires the Corporation and/or all or substantially all of its assets or business (whether pursuant to a stock purchase, an asset purchase, a merger or any other similar transaction), and in consideration for such acquisition issues to the former stockholders of the Corporation shares of capital stock of such shell company.

6. Voting.

(a) Subject to any separate voting rights provided for herein or otherwise required by law, the holders of New Preferred Stock shall be entitled to vote, together with the holders of Common Stock as one class, on all matters as to which holders of Common Stock shall be entitled to vote, in the same manner and with the same effect as such holders of Common Stock. In any such vote, each share of

New Preferred Stock shall entitle the holder thereof to the number of votes per share that equals the number of shares of Common Stock (including fractional shares) into which each such share of New Preferred Stock is then convertible, rounded up to the nearest one-tenth of a share, but not including any shares of Common Stock issuable upon conversion of any dividends accrued on such New Preferred Stock.

(b) In addition to the rights specified in Section B.6(a):

(i) for so long as any shares of Series A-1 Stock are outstanding, the holders of a majority of the shares of Series A-1 Stock outstanding, voting as a separate class, shall have the right to elect two (2) members of the Board of Directors of the Corporation; and

(ii) Oxford Bioscience Partners IV L.P. (including for this purpose, members of the Oxford/Saints Group (as defined in the Stockholders’ Agreement), HealthCare Ventures or Wellcome Trust (collectively, the “G3 Holders”) voting as a separate class shall have the right to elect one (1) member of the Board of Directors of the Corporation by majority vote of the shares of Series A-1 Stock held by them; provided, however, that in order to be eligible to vote or consent with respect to the election of such member of the Board of Directors, a G3 Holder together with members of such G3 Holders’ Group (as defined in the Stockholders’ Agreement) must hold greater than twenty percent (20%) of the shares of Series A-1 Stock purchased under the Series A-1 Stock Purchase Agreement by such G3 Holder and the members of such G3 Holders’ Group; and

(c) In any election of New Preferred Directors pursuant to Section B.6(b), each holder of New Preferred Stock eligible to participate in the election of New Preferred Directors shall be entitled to one vote for each share of Common Stock (including fractional shares) into which each such share of New Preferred Stock held by such holder is then convertible, rounded up to the nearest one-tenth of a share (determined as set forth in the second sentence of Section B.6(a) hereof), and no holder of New Preferred Stock shall be entitled to cumulate its votes by giving one candidate more than one vote per share. The voting right of the Series A-1 Stockholders, the G3 Holders and the MPM Holder contained in Section B.6(b), may be exercised at a special meeting of the applicable holders of New Preferred Stock called as provided in accordance with the by-laws of the Corporation, at any annual or special meeting of the stockholders of the Corporation, or by written consent of such applicable holders of New Preferred Stock in lieu of a meeting.

The number of directors constituting the entire membership of the Board of Directors of the Corporation shall be set by the Board of Directors pursuant to the By-Laws of the Corporation.

(d) A vacancy in the directorships elected by the Series A-1 Stockholders, the G3 Holders or the MPM Holder pursuant to Section B.6(b), may be filled by a vote at a meeting called in accordance with the by-laws of the Corporation or written consent in lieu of such meeting of the applicable holders of New Preferred Stock, respectively or by the remaining directors as provided in the by-laws of the Corporation.

(e) The holders of capital stock of the corporation, voting as a single class, shall elect the remaining member or members of the Board of Directors of the Corporation. In any election of directors pursuant to this Section B.6(e), each stockholder shall be entitled to one vote for each share of Common Stock held or, if New Preferred Stock, into which each such share of New Preferred Stock is then convertible (determined in accordance with Section B.6(a) hereof), and no stockholder shall be entitled to cumulate its votes by giving one candidate more than one vote per share. The voting right of the stockholders contained in this Section B.6(e) may be exercised at a special meeting of the stockholders called as provided in accordance with the by-laws of the Corporation, at any annual or special meeting of the stockholders of the Corporation, or by written consent of the stockholder in lieu of a meeting. The director or directors elected pursuant to this Section B.6(e) shall serve from the date of their election and qualification until their successors have been duly elected and qualified.

(f) A vacancy in the directorship or directorships elected by the stockholders pursuant to Section B.6(e), may be filled by a vote at a meeting called in accordance with the by-laws of the Corporation or written consent in lieu of such meeting of the stockholders of the Corporation or by the remaining directors as provided in the by-laws of the Corporation.

(g) Except as otherwise expressed, implied or contemplated in this Certificate, the Series A-1 Purchase Agreement or the Merger Agreement, the Corporation shall not, directly or indirectly, through a merger, consolidation, reorganization or otherwise, without the affirmative approval of the New Senior Majority acting separately from the holders of Common Stock or any other securities of the Corporation, given by written consent in lieu of a meeting or by vote at a meeting called for such purpose, for which meeting or approval by written consent timely and specific notice in the manner provided in the by-laws of the Corporation shall have been given to each Series A-1 Stockholder, Series A-2 Stockholder and Series A-3 Stockholder to do the following:

The foregoing approval shall be obtained in addition to any approval required by law. For purposes of clarification, the creation, authorization or issuance of any new class or series of capital stock of the Corporation having rights, preferences or privileges senior to or on a parity with the Series A-1 Stock (and any amendment to the certificate of incorporation of the Company for purposes of creating or authorizing such new class or series of capital stock) shall not be deemed or treated as materially adversely affecting the Series A-1 Stock.

(k) Except as otherwise expressed, implied or contemplated in this Certificate, the Series A-1 Purchase Agreement or the Merger Agreement, the Corporation shall not, directly or indirectly, through a merger, consolidation, reorganization or otherwise, without the affirmative approval of holders of a majority of the then outstanding shares of Series A-4 Stock, acting separately from the holders of Common Stock or any other securities of the Corporation, given by written consent in lieu of a meeting or by vote at a meeting called for such purpose, for which meeting or approval by written consent timely and specific notice in the manner provided in the by-laws of the Corporation shall have been given to each holder of such Series A-4 Stock, amend, alter or repeal any provision of this Certificate if such amendment, alteration or repeal would (i) alter or change the rights, preferences or privileges of the Series A-4 Stock in a manner that materially adversely affects the Series A-4 Stock and such amendment does not change or alter the comparable rights, preferences or privileges of any other series of New Preferred Stock in a manner that materially adversely affects such other series of New Preferred Stock or (ii) increases or decreases the authorized number of shares of Series A-4 Stock.

7. Conversion.

(a) Any New Preferred Stockholder shall have the right, at any time or from time to time, to convert any or all of its shares of New Preferred Stock into that number of fully paid and nonassessable shares of Common Stock for each share of New Preferred Stock so converted equal to the quotient of the Series A-1 Original Purchase Price, Series A-2 Original Purchase Price, Series A-3 Original Purchase Price, Series A-4 Original Purchase Price, Series A-6 Original Purchase Price or Series A-6 Original Purchase Price, as applicable, for such share divided by the Series A-1 Conversion Price, the Series A-2 Conversion Price, Series A-3 Conversion Price, Series A-4 Conversion Price, Series A-5 Conversion Price or the Series A-6 Conversion Price (each as defined in Section B.7(e)(i) hereof), as applicable, for such share of New Preferred Stock, as last adjusted and then in effect, rounded up to the nearest one-tenth of a share; provided, however, that cash shall be paid in lieu of the issuance of fractional shares of Common Stock, as provided in Section B.7(d) hereof.

(b) (i) Any New Preferred Stockholder who exercises the right to convert shares of New Preferred Stock into shares of Common Stock pursuant to this Section B.7 shall be entitled to payment of all accrued dividends, whether or not declared and all declared but unpaid dividends payable with respect to such New Preferred Stock pursuant to Section B.3 herein, up to and including the Conversion Date (as defined in Section B.7(b)(iii) hereof).

(ii) Any New Preferred Stockholder may exercise the right to convert such shares into Common Stock pursuant to this Section B.7 by delivering to the Corporation during regular business hours, at the office of the Corporation or any transfer agent of the Corporation or at such other place as may be designated by the Corporation, the certificate or certificates for the shares to be converted (the “New Preferred Certificate”), duly endorsed or assigned in blank to the Corporation (if required by it) or an affidavit of loss as to the same.

(iii) Each New Preferred Certificate shall be accompanied by written notice stating that such holder elects to convert such shares and stating the name or names (with address) in which the certificate or certificates for the shares of Common Stock (the “Common Certificate”) are to be issued. Such conversion shall be deemed to have been effected on the date when such delivery is made, and such date is referred to herein as the “Conversion Date.”

(iv) As promptly as practicable thereafter, the Corporation shall issue and deliver to or upon the written order of such holder, at the place designated by such holder, (A) a Common Certificate for the number of full shares of Common Stock to which such holder is entitled and (B) a check or cash in respect of any fractional interest in shares of Common Stock to which such holder is entitled, as provided in Section B.7(d) hereof, payable with respect to the shares so converted up to and including the Conversion Date.

(v) The person in whose name the Common Certificate or Certificates are to be issued shall be deemed to have become a holder of record of Common Stock on the applicable

Conversion Date, unless the transfer books of the Corporation are closed on such Conversion Date, in which event the holder shall be deemed to have become the stockholder of record on the next succeeding date on which the transfer books are open, provided that the Series A-1 Conversion Price, the Series A-2 Conversion Price, Series A-3 Conversion Price, Series A-4 Conversion Price, the Series A-5 Conversion Price or the Series A-6 Conversion Price, as applicable, upon which the conversion shall be executed shall be that in effect on the Conversion Date.

(vi) Upon conversion of only a portion of the number of shares covered by a New Preferred Certificate, the Corporation shall issue and deliver to or upon the written order of the holder of such New Preferred Certificate, at the expense of the Corporation, a new certificate covering the number of shares of New Preferred Stock representing the unconverted portion of the New Preferred Certificate, which new certificate shall entitle the holder thereof to all the rights, powers and privileges of a holder of such New Preferred Stock.

(c) If a New Preferred Stockholder shall surrender more than one share of the same class of New Preferred Stock for conversion at any one time, then the number of full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of New Preferred Stock so surrendered.

(d) No fractional shares of Common Stock shall be issued upon conversion of New Preferred Stock. The Corporation shall instead pay a cash adjustment for any such fractional interest in an amount equal to the Current Market Price thereof on the Conversion Date, as determined in accordance with Section B.7(e)(vi) hereof.

(e) For all purposes of this Article III, Part B, the initial conversion price of the Series A-1 Stock shall be the Series A-1 Original Purchase Price, the initial conversion price of the Series A-2 Stock shall be the Series A-2 Original Purchase Price, the initial conversion price of the Series A-3 Stock shall be the Series A-3 Original Purchase Price, the initial conversion price of the Series A-4 Stock shall be the Series A-4 Original Purchase Price, the initial conversion price of the Series A-5 Stock shall be the Series A-5 Original Purchase Price, and the initial conversion price of the Series A-6 Stock shall be the Series A-6 Original Purchase Price, in each case subject to adjustment from time to time as follows (the conversion price of any or each of the Series A-1 Stock, the Series A-2 Stock, the Series A-3 Stock, the Series A-4 Stock, the Series A-5 Stock and the Series A-6 Stock is sometimes referred to generically in this Section B.7 as the “Conversion Price”):

(i) Subject to Section B.7(e)(ii) and B.7(e)(x) below, if the Corporation shall, at any time or from time to time after the Series A-1 Original Issuance Date, issue or sell any shares of Common Stock (which term, for purposes of this Section B.7(e)(i), including all subsections thereof, shall be deemed to include all other securities convertible into, or exchangeable or exercisable for, shares of Common Stock (including, but not limited to, Preferred Stock) or options to purchase or other rights to subscribe for such convertible or exchangeable securities, in each case other than Excluded Stock (as defined in Section B.7(e)(ii) below), for a consideration per share less than the Series A-1 Conversion Price in effect immediately prior to the issuance of such Common Stock or other securities (a “New Dilutive Issuance”), then (X) the Conversion Price of the Series A-1 Stock (the “Series A-1 Conversion Price”) in effect immediately prior to each such New Dilutive Issuance shall automatically be reduced to a price equal to the product obtained by multiplying such Series A-1 Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for the additional stock so issued would purchase at

such Series A-1 Conversion Price as in effect immediately prior to such issuance, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of additional stock so issued, (Y) the Conversion Price for the Series A-2 Stock (the “Series A-2 Conversion Price”) in effect immediately prior to each such New Dilutive Issuance shall automatically be reduced to a price equal to the product obtained by multiplying such Series A-2 Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for the additional stock so issued would purchase at such Series A-2 Conversion Price as in effect immediately prior to such issuance, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of additional stock so issued, and (Z) the Conversion Price for the Series A-3 Stock (the “Series A-3 Conversion Price”) in effect immediately prior to each such New Dilutive Issuance shall automatically be reduced to a price equal to the product obtained by multiplying such Series A-3 Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of Common Stock that the aggregate consideration received by the Corporation for the additional stock so issued would purchase at such Series A-3 Conversion Price as in effect immediately prior to such issuance, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, shares of Common Stock issued or issuable upon conversion of the outstanding Preferred Stock, but excluding shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock) plus the number of shares of additional stock so issued. For purposes of this Section B.7(e)(i), the number of shares of Common Stock deemed issuable upon conversion of such outstanding shares of Existing Preferred Stock shall be determined without giving effect to any adjustments to the applicable Conversion Price resulting from the New Dilutive Issuance that is the subject of this calculation. For purposes of Part B of this Certificate, the term “Series A-4 Conversion Price” shall mean the Conversion Price of the Series A-4 Stock, the term “Series A-5 Conversion Price” shall mean the Conversion Price of the Series A-5 Stock and the term “Series A-6 Conversion Price” shall mean the Conversion Price of the Series A-6 Stock. For the purposes of any adjustment of the Conversion Price pursuant to this Section B.7(e)(i), the following provisions shall be applicable.

a. In the case of the issuance of Common Stock in whole or in part for cash, the consideration shall be deemed to be the amount of cash paid therefor after deducting therefrom any discounts, commissions or other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with the issuance and sale thereof, plus the value of any property other than cash received by the Corporation, determined as provided in Section B.7(e)(i)(b) hereof, plus the value of any other consideration received by the Corporation determined as set forth in Section B.7(e)(i)(c) hereof.

Directors, irrespective of any accounting treatment; provided, however, that such fair market value of such property as determined by the Board of Directors shall not exceed the aggregate Current Market Price (as defined in Section B.7(e)(viii) hereof) of the shares of Common Stock or such other securities being issued, less any cash consideration paid for such shares, determined as provided in Section B.7(e)(i)(a) hereof and less any other consideration received by the Corporation for such shares, determined as set forth in Section B.7(e)(i)(c) hereof.

i. the aggregate maximum number of shares of Common Stock deliverable upon exercise of such options to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in Sections B.7(e)(i)(a), (b) and (c) hereof), if any, received by the Corporation upon the issuance of such options or rights plus the minimum purchase price provided in such options or rights for the Common Stock covered thereby (the consideration in each case to be determined in the manner provided in Sections B.7(e)(i)(a), (b) and (c) hereof);

B.7(e)(i)(d)(iii) hereof is reversed or terminated, or expires), then the applicable Conversion Price shall be automatically readjusted to the applicable Conversion Price that would have been obtained had such options, rights or convertible or exchangeable securities not been issued; and

v. if the terms of any option or convertible security (excluding options or convertible securities which, upon exercise, conversion or exchange thereof, would entitle the holder thereof to receive shares of Common Stock which are Excluded Stock), the issuance of which was not a New Dilutive Issuance, are revised after the Series A-1 Original Issuance Date (either automatically pursuant the provisions contained therein or as a result of an amendment to such terms) to provide for either (1) any increase in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any such option or convertible security or (2) any decrease in the consideration payable to the Corporation upon such exercise, conversion or exchange, then such option or convertible security, as so amended, and the shares of Common Stock subject thereto shall be deemed to have been issued effective upon such increase or decrease becoming effective.

(ii) “Excluded Stock” shall mean:

a. Common Stock issued upon conversion of any shares of Preferred Stock, including any shares of Common Stock issuable upon conversion of any dividends accrued on such Preferred Stock;

b. Common Stock issued or issuable to officers, directors or employees of or consultants or independent contractors to the Corporation, pursuant to any written agreement, plan or arrangement to purchase, or rights to subscribe for, such Common Stock, including Common Stock issued under the Corporation’s 2003 Long-Term Incentive Plan, as amended, or other equity incentive plan or other agreements that have been approved in form and in substance by the New Senior Majority, calculated in accordance with Section B.6(a) of Article III herein (including, in such calculation, any outstanding restricted stock awards held by such holders), and which, as a condition precedent to the issuance of such shares, provide for the vesting of such shares and subject such shares to restrictions on transfer and rights of first offer in favor of the Corporation, and restricted stock grants to directors, employees or consultants as approved by the Board of Directors of the Corporation; provided, however, that the maximum number of shares of Common Stock heretofore or hereafter issuable pursuant to the Corporation’s 2003 Long-Term Incentive Plan, as amended, and all such agreements, plans and arrangements shall not exceed 2,015,666 shares of Common Stock;

c. Common Stock issued as a stock dividend or distribution on the Preferred Stock payable in shares of Common Stock, or capital stock of any other class issuable upon any subdivision, recombination, split-up or reverse stock split of all the outstanding shares of such class of capital stock;

e. Common Stock or other securities issued or issuable to third parties in connection with strategic partnerships or alliances, corporate partnerships, joint ventures or other licensing transactions, provided that each such transaction and related issuance is approved by the Board of Directors, including, but not limited to, (A) any shares of Preferred Stock or Common Stock issued or issuable to Ipsen Pharma SAS (“Ipsen”), pursuant to the terms of that certain License Agreement, as amended and may be amended with the approval of the Board of Directors of the Corporation and in effect from time to time, by and between the Corporation and Ipsen as payment for milestones in lieu of cash payments and (B) shares of Series A-5 Stock issued or issuable pursuant to that certain Stock Issuance Agreement as of March 29, 2011 by and between the Corporation and Nordic Bioscience and the letter agreement as of March 29, 2011 by and between the Corporation and Nordic Bioscience, pursuant to which the Corporation will issue shares of the Corporation’s Series A-5 Convertible Preferred Stock, $0.01 par value per share and the issuance of Series A-6 Stock issued or to be issued as dividends on such Series A-5 Stock, and shares of Common Stock issuable upon conversion of any such shares of Series A-5 Stock and Series A-6 Stock;

g. Common Stock or other securities, the issuance of which is approved by the New Senior Majority, with such approval expressly waiving the application of the anti-dilution provisions of this Section B.7 as a result of such issuance;

h. Preferred Stock or Common Stock issued or issuable pursuant to any warrant outstanding as of the date hereof or any warrant and any shares of Preferred Stock or common stock, or common stock issued upon exercise of any Preferred Stock, issued in connection with the Qualified Financing, including, but not limited to a warrant for shares of Series A-1 Preferred Stock issued or issuable to Leerink Swan, any shares of Preferred Stock or Common Stock upon exercise thereof and any Common Stock issuable upon conversion of such Preferred Stock issued upon exercise thereof; and

i. All shares of New Preferred Stock and Common stock issued in connection with the Qualified Financing as provided in this Certificate and the Series A-1 Purchaser Agreement, and all shares of Common Stock issued or issuable upon conversion of any such shares of New Preferred Stock.

(iii) If the number of shares of Common Stock outstanding at any time after the Series A-1 Original Issuance Date (as defined in Section B.8) is increased by a stock dividend payable in shares of Common Stock or by a subdivision or split-up of shares of Common Stock, then, following the record date fixed for the determination of holders of Common Stock entitled to receive such stock dividend, subdivision or split-up, the applicable Conversion Price shall be appropriately decreased in the form of a Proportional Adjustment (as defined in Section B.8) so that the number of shares of Common Stock issuable on conversion of each share of New Preferred Stock shall be increased in proportion to such increase in outstanding shares.

(iv) If the number of shares of Common Stock outstanding at any time after the Series A-1 Original Issuance Date is decreased by a combination of the outstanding shares of Common Stock

(other than pursuant to the Reverse Split), then, following the record date for such combination, the applicable Conversion Price shall be appropriately increased in the form of a Proportional Adjustment so that the number of shares of Common Stock issuable on conversion of each share of New Preferred Stock shall be decreased in proportion to such decrease in outstanding shares.

(v) Except as otherwise contemplated in the Series A-1 Purchase Agreement, if at any time after the Series A-1 Original Issuance Date, the Corporation shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Corporation (other than shares of Common Stock) or in cash or other property, then and in each such event provision shall be made so that the holders of the New Preferred Stock shall receive upon conversion thereof in addition to the number of shares of Common Stock receivable thereupon, the kind and amount of securities of the Corporation, cash or other property which they would have been entitled to receive had the New Preferred Stock been converted into Common Stock on the date of such event and had they thereafter, during the period from the date of such event to and including the conversion date, retained such securities receivable by them as aforesaid during such period, giving application to all adjustments called for during such period under this paragraph with respect to the rights of the holders of the New Preferred Stock; and provided further, however, that no such adjustment shall be made if the holders of New Preferred Stock simultaneously receive a dividend or other distribution of such securities, cash, or other property in an amount equal to the amount of such securities, cash, or other property as they would have received if all outstanding shares of New Preferred Stock had been converted into Common Stock on the date of such event.

(vi) Subject to the provisions of Section B.4(i) above, in the event, at any time after the Series A-1 Original Issuance Date, of any capital reorganization, or any reclassification of the capital stock of the Corporation (other than pursuant to the Reverse Split, other than as contemplated under this Certificate and the Series A-1 Purchase Agreement and other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), or the consolidation or merger of the Corporation with or into another person (other than pursuant to the Merger Agreement and other than a consolidation or merger in which the Corporation is the continuing corporation and which does not result in any change in the powers, designations, preferences and rights, or the qualifications, limitations or restrictions, if any, of the capital stock of the Corporation) or of the sale or other disposition of all or substantially all the properties and assets of the Corporation in their entirety to any other person (any such transaction, an “Extraordinary Transaction”), then the Corporation shall provide appropriate adjustment in the form of a Proportional Adjustment to the applicable Conversion Price with respect to each share of New Preferred Stock outstanding after the effectiveness of such Extraordinary Transaction such that each share of New Preferred Stock outstanding immediately prior to the effectiveness of the Extraordinary Transaction shall be convertible into the kind and number of shares of stock or other securities or property of the Corporation, or of the corporation resulting from or surviving such Extraordinary Transaction, that a holder of the number of shares of Common Stock deliverable (immediately prior to the effectiveness of the Extraordinary Transaction) upon conversion of such share of New Preferred Stock would have been entitled to receive upon such Extraordinary Transaction. The provisions of this Section B.7(e)(vi) shall similarly apply to successive Extraordinary Transactions.

(vii) All calculations under this Section B.7(e) shall be made to the nearest one-tenth of a cent ($.001) or to the nearest one-tenth of a share, as the case may be.

(viii) For the purpose of any computation pursuant to Section B.7(d), Section B.3(a) hereof or this Section B.7(e), the “Current Market Price” at any date of one share of Common Stock shall be defined as the average of the daily closing prices for the 20 consecutive Business Days ending on the fifth (5th) Business Day before the day in question (as adjusted for any stock dividend, split-up,

combination or reclassification that took effect during such 20 Business Day period), determined as follows:

c. If the Common Stock is not traded in such manner that the quotations referred to in this Section B.7(d)(viii) are available for the period required hereunder, then the Current Market Price shall be the fair market value of such share, as determined in good faith by a majority of the entire Board of Directors.

(ix) In any case in which the provisions of this Section B.7(e) shall require that an adjustment shall become effective immediately after a record date for an event, the Corporation may defer until the occurrence of such event (A) issuing to the holder of any shares of New Preferred Stock converted after such record date and before the occurrence of such event the additional shares of capital stock issuable upon such conversion by reason of the adjustment required by such event over and above the shares of capital stock issuable upon such conversion before giving effect to such adjustment, and (B) paying to such holder any cash amounts in lieu of fractional shares pursuant to Section B.7(d) hereof; provided, however, that the Corporation shall deliver to such holder a due xxxx or other appropriate instrument evidencing such holder’s right to receive such additional shares and such cash upon the occurrence of the event requiring such adjustment.

(x) If a state of facts shall occur that, without being specifically controlled by the provisions of this Section B.7, would not fairly protect the conversion rights of the holders of the New Preferred Stock in accordance with the essential intent and principles of such provisions, then the Board of Directors shall make an adjustment in the application of such provisions, in accordance with such essential intent and principles, so as to protect such conversion rights.

(f) Whenever the applicable Conversion Price shall be adjusted as provided in Section B.7(e) hereof, the Corporation shall forthwith file and keep on record at the office of the Secretary of the Corporation and at the office of its transfer agent or at such other place as may be designated by the Corporation, a statement, signed by both its President or Chief Executive Officer and its Treasurer or Chief Financial Officer, showing in detail the facts requiring such adjustment and the applicable Conversion Price that shall be in effect after such adjustment. The Corporation shall also cause a copy of such statement to be sent by first-class, certified mail, return receipt requested, postage prepaid, to each New Preferred Stockholder at such holder’s address appearing on the Corporation’s records. Where appropriate, such copy shall be given in advance of any such adjustment and shall be included as part of a notice required to be mailed under the provisions of Section B.7(g) hereof.

(g) In the event the Corporation shall propose to take any action of the types described in Section B.7(e)(i), (iii), (iv) or (v) hereof, or any other Event of Sale, other then the transactions contemplated by the Series A-1 Purchase Agreement and the Merger Agreement, the Corporation shall give

notice to each New Preferred Stockholder in the manner set forth in Section B.7(f) hereof, which notice shall specify the record date, if any, with respect to any such action and the date on which such action is to take place. Such notice shall also set forth such facts with respect thereto as shall be reasonably necessary to indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the applicable Conversion Price with respect to the New Preferred Stock, and the number, kind or class of shares or other securities or property which shall be deliverable or purchasable upon each conversion of New Preferred Stock. In the case of any action (other than any action contemplated or required by the Series A-1 Purchase Agreement or Merger Agreement) that would require the fixing of a record date, such notice shall be given at least 20 days prior to the record date so fixed, and in the case of any other action, such notice shall be given at least 30 days prior to the taking of such proposed action.

(h) The Corporation shall pay all documentary, stamp or other transactional taxes attributable to the issuance or delivery of shares of capital stock of the Corporation upon conversion of any shares of New Preferred Stock; provided, however, that the Corporation shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificate for such shares in a name other than that of the New Preferred Stockholder in respect of which such shares of New Preferred Stock are being issued.

(i) The Corporation shall reserve out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the New Preferred Stock, sufficient shares of Common Stock to provide for the conversion of all outstanding shares of New Preferred Stock.

8. Definitions. As used in this Part B of Article III of this Certificate, the following terms shall have the corresponding meanings:

Notwithstanding the foregoing, the Reverse Split shall not trigger or give rise to any Proportional Adjustment.

9. Forced Conversion and Forfeiture Upon Failure to Perform Future Funding Obligations Pursuant to the Series A-1 Purchase Agreement.

(a) Trigger Event. In the event that an Investor (as defined in the Series A-1 Purchase Agreement) does not timely and completely fulfill his, her or its Future Funding Obligations (as defined in the Series A-1 Purchase Agreement) in the Qualified Financing pursuant to the terms of Series A-1 Purchase Agreement, then (i) all shares of New Preferred Stock then held by such Investor shall automatically, and without any further action on the part of such Investor, be converted into shares of Common Stock at a rate of 1 share of Common Stock for every 10 shares of New Preferred Stock to be so converted and (ii) the Corporation shall have the right to repurchase and such holders shall be required to sell all shares of Common Stock issued upon conversion (either pursuant to the foregoing clause (i) or otherwise) of all Additional A-1 Preferred Stock (as defined in the Series A-1 Purchase Agreement), all Series A-2 Stock, all Series A-3 Stock and all Series A-4 Stock issued to such Investor pursuant to the Automatic Reclassification (as defined in the Series A-1 Purchase Agreement) (the “Repurchased Shares”) for a per share purchase price equal to the par value of such Repurchased Share and all such Repurchased Shares shall thereafter be cancelled by the Corporation and no longer be issued and outstanding shares of capital stock of the Corporation, in accordance with Section 4(e) of the Series A-1 Purchase Agreement and Section 9.(b) below. The conversion and repurchase of shares to the Corporation set forth in this Section 9.(a) is referred to as a “Subsequent Closing Adjustment”.

(b) Procedural Requirements. Upon a Subsequent Closing Adjustment, each holder of shares of New Preferred Stock converted pursuant to Section B.9(a) shall be sent written notice of such Subsequent Closing Adjustment and the place designated for mandatory conversion of all such shares of New Preferred Stock and the repurchase of all Repurchased Shares. Upon receipt of such notice, each holder of such shares of New Preferred Stock and Repurchased Shares shall surrender his, her or its certificate or certificates for all such shares (or, if such holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to

indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation at the place designated in such notice. If so required by the Corporation, certificates surrendered for conversion or repurchase shall be endorsed or accompanied by written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. All rights with respect to the New Preferred Stock so converted or such Repurchased Shares to be repurchased, including the rights, if any, to receive notices and vote (other than as a holder of shares of Common Stock that are not Repurchased Shares), will terminate at the time of the failure to fulfill the obligations of any Closing (as defined in the Series A-1 Purchase Agreement) (notwithstanding the failure of the holder or holders thereof to surrender the certificates for such shares at or prior to such time), except only the rights of the holders thereof, upon surrender of their certificate or certificates therefor (or lost certificate affidavit and agreement), to receive the items provided for in the next sentence of this Section B.9(b). As soon as practicable after the surrender of the certificate or certificates (or lost certificate affidavit and agreement) for New Preferred Stock so converted that is not included among the Repurchased Shares, the Corporation shall issue and deliver to such holder, or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable on such conversion in accordance with the provisions hereof, together with cash as provided in B.7(d) in lieu of any fraction of a share of Common Stock otherwise issuable upon such conversion and the payment of any declared but unpaid dividends on the shares of New Preferred Stock converted. Such converted New Preferred Stock, together with all Repurchased Shares pursuant to B.9(a)(ii) shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of New Preferred Stock and Common Stock accordingly.

10. Special Mandatory Conversion.

(a) Trigger Events. Each share of New Preferred Stock shall be automatically converted into fully paid and non-assessable shares of Common Stock at the then-effective applicable Conversion Price in the event that (i) the New Senior Majority shall have elected to convert all shares of New Preferred Stock or (2) the Common Stock of the Corporation becomes listed for trading on a national securities exchange. Each of the conversions set forth in this Section B.10(a) is referred to as a “Special Mandatory Conversion.” All accrued but unpaid dividends on shares New Preferred Stock shall be paid, in cash or additional shares at the discretion of the Board of Directors, in connection with any Special Mandatory Conversion.

(b) Procedural Requirements. Upon a Special Mandatory Conversion, each holder of shares of New Preferred Stock converted pursuant to Section B.10(a) shall be sent written notice of such Special Mandatory Conversion and the place designated for mandatory conversion of all shares of New Preferred Stock. Upon receipt of such notice, each holder of such shares of New Preferred Stock shall surrender his, her or its certificate or certificates for all such shares (or, if such holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation at the place designated in such notice. If so required by the Corporation, certificates surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. All rights with respect to the New Preferred Stock so converted, including the rights, if any, to receive notices and vote (other than as a holder of Common Stock), will terminate at the time of the Special Mandatory Conversion (notwithstanding the failure of the holder or holders thereof to surrender the certificates for such shares at or prior to such time), except only the rights of the holders thereof, upon surrender of their certificate or certificates therefor (or lost certificate affidavit and agreement), to receive

the items provided for in the next sentence of this Section B.10(b). As soon as practicable after the Special Mandatory Conversion and the surrender of the certificate or certificates (or lost certificate affidavit and agreement) for New Preferred Stock so converted, the Corporation shall issue and deliver to such holder, or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable on such conversion in accordance with the provisions hereof, together with cash as provided in B.7(d) in lieu of any fraction of a share of Common Stock otherwise issuable upon such conversion and the payment of any declared but unpaid dividends on the shares of New Preferred Stock converted, and a new certificate for the number of shares, if any, of New Preferred Stock represented by such surrendered certificate and not converted pursuant to B.10(a). Such converted New Preferred Stock shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of New Preferred Stock accordingly.

(c) Duration of Section. This Section B.10 and the rights and obligations of the parties hereunder shall automatically terminate on the consummation of a Liquidation or an Event of Sale.

Such authorized shares of Common Stock may be increased or decreased (but not below the combined number of shares thereof then outstanding and those reserved for issuance upon conversion of the Preferred Stock) by the affirmative vote of the holders of the majority of the stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the Delaware General Corporation Law.

SECTION 2. Certain Covenants of the Corporation.

2.1 Meetings of the Board of Directors. The Corporation shall call, and use its best efforts to have, regular meetings of the Board not less often than quarterly. The Corporation shall promptly pay all reasonable and appropriately documented travel expenses and other out-of-pocket expenses incurred by directors who are not employed by the Corporation in connection with attendance at meetings to transact the business of the Corporation or attendance at meetings of the Board or any committee thereof.

2.2 Reservation of Shares of Common Stock and Preferred Stock, Etc. The Corporation shall at all times have authorized and reserved out of its authorized but unissued shares of Common Stock a sufficient number of shares of Common Stock to provide for the conversion of the Preferred Shares. Neither the issuance of the Preferred Shares nor the shares of Common Stock issuable upon the conversion of the Preferred Shares shall be subject to a preemptive right of any other Stockholder.

2.3 Right of First Refusal.

(a) The Corporation shall not issue, sell or exchange, agree to issue, sell or exchange, or reserve or set aside for issuance, sale or exchange, any Offered Securities, unless in each

case the Corporation shall have first offered to sell to the Series A-1 Stockholders, Series A-2 Stockholders and the Series A-3 Stockholders (collectively, the “ROFR Stockholders”) all of such Offered Securities on the terms set forth herein. Each ROFR Stockholder shall be entitled to purchase up to its Equity Percentage of the Offered Securities. Each ROFR Stockholder may delegate its rights and obligations with respect to such Offer to one or more members of its Group, which members shall thereafter be deemed to be “ROFR Stockholders” for the purpose of applying this Section 2.3 to such Offer.

(b) The Corporation shall deliver to each ROFR Stockholder written notice of the offer to sell the Offered Securities, specifying the price and terms and conditions of the offer (the “Offer”). The Offer by its terms shall remain open and irrevocable for a period of 30 days from the date of its delivery to such ROFR Stockholders (the “30-Day Period”), subject to extension to include the Excess Securities Period (as such term is hereinafter defined).

(c) Each ROFR Stockholder shall evidence its intention to accept the Offer by delivering a written notice signed by such ROFR Stockholder, as applicable, setting forth the number of shares that such ROFR Stockholder elects to purchase (the “Notice of Acceptance”). The Notice of Acceptance must be delivered to the Corporation prior to the end of the 30-Day Period. The failure by a ROFR Stockholder to exercise its rights hereunder shall not constitute a waiver of any other rights or of the right to receive notice of and participate in any subsequent Offer.

(d) If any ROFR Stockholder fails to exercise its right hereunder to purchase its Equity Percentage of the Offered Securities, the Corporation shall so notify the other ROFR Stockholders in a written notice (the “Excess Securities Notice”). The Excess Securities Notice shall be given by the Corporation promptly after it learns of the intention of any ROFR Stockholder not to purchase all of its Equity Percentage of the Offered Securities, but in no event later than ten (10) business days after the expiration of the 30-Day Period. The ROFR who or which have agreed to purchase their Equity Percentage of the Offered Securities shall have the right to purchase the portion not purchased by such ROFR Stockholders (the “Excess Securities”), on a pro rata basis, by giving notice within ten (10) business days after receipt of the Excess Securities Notice from the Corporation. The twenty (20) business day period during which (i) the Corporation must give the Excess Securities Notice to the applicable ROFR Stockholders, and (ii) each of them must then give the Corporation notice of their intention to purchase all or any portion of their pro rata share of the its Excess Securities, is hereinafter referred to as the “Excess Securities Period.”

(e) If the ROFR Stockholders tender their Notice of Acceptance prior to the end of the 30-Day Period, indicating their intention to purchase all of the Offered Securities, or, if prior to the termination of the Excess Securities Period the ROFR Stockholders tender Excess Securities Notices to purchase all of the Excess Securities, the Corporation shall schedule a closing of the sale of all such Offered Securities. Upon the closing of the sale of the Offered Securities to be purchased by the ROFR Stockholders and the Excess Securities to be purchased by ROFR Stockholders, each ROFR Stockholder shall (i) purchase from the Corporation that portion of the Offered Securities and Excess Securities, as applicable, for which it tendered a Notice of Acceptance and an Excess Securities Notice, as applicable, upon the terms specified in the Offer, and (ii) execute and deliver an agreement further restricting transfer of such Offered Securities substantially as set forth in Section 3.1, 3.2 and 3.3 of this Agreement. In addition, with respect to the Offered Securities and Excess Securities being purchased by the ROFR Stockholders, the Corporation shall provide each such ROFR Stockholder with the rights and benefits set forth in this Agreement. The obligation of the ROFR Stockholders to purchase such Offered Securities and Excess Securities, as applicable, is further conditioned upon the preparation of a purchase agreement embodying the terms of the Offer, which shall be reasonably satisfactory in form and substance to such ROFR Stockholder and each of their respective counsels.

(f) The Corporation shall have ninety (90) days from the expiration of the 30-Day Period, or the Excess Securities Period, if applicable, to sell the Offered Securities (including the Excess Securities) refused by the ROFR Stockholders (the “Refused Securities”) to any other person or persons, but only upon terms and conditions which are in all material respects (including, without limitation, price and interest rate) no more favorable to such other person or persons, and no less favorable to the Corporation, than those set forth in the Offer. Upon and subject to the closing of the sale of all of the Refused Securities (which shall include full payment to the Corporation), each ROFR Stockholder shall (i) purchase from the Corporation those Offered Securities and Excess Securities, as applicable, for which it tendered a Notice of Acceptance and an Excess Securities Notice, if applicable, upon the terms specified in the Offer, and (ii) execute and deliver an agreement restricting transfer of such Offered Securities and Excess Securities, as applicable, substantially as set forth in Sections 3.1, 3.2 and 3.3 of this Agreement. In addition, with respect to the Offered Securities or Excess Securities being purchased by the ROFR Stockholders, the Corporation shall provide each such ROFR Stockholder with the rights and benefits set forth in this Agreement. The Corporation agrees, as a condition precedent to accepting payment for and making delivery of any Refused Securities to any executive officer, employee, consultant or independent contractor of or to the Corporation, or to any other person, to have each and every such person execute and deliver this Agreement, as may be modified or amended from time to time pursuant to Section 11 hereof, to the extent such purchaser has not already executed this Agreement. The obligation of the ROFR Stockholders to purchase such Offered Securities and Excess Securities, as applicable, is further conditioned upon the preparation of a purchase agreement embodying the terms of the Offer, which shall be reasonably satisfactory in form and substance to such ROFR Stockholder and each of their respective counsels.

(g) In each case, any Offered Securities not purchased either by the ROFR Stockholders or by any other person in accordance with this Section 2.3 may not be sold or otherwise disposed of until they are again offered to the ROFR Stockholders under the procedures specified in Paragraphs (a), (b), (c), (d), (e) and (f) hereof.

(h) Each ROFR Stockholder may, by prior written consent, waive its rights under this Section 2.3. Such a waiver shall be deemed a limited waiver and shall only apply to the extent specifically set forth in the written consent of such ROFRR Stockholder.

(i) This Section 2.3 and the rights and obligations of the parties hereunder shall automatically terminate on the consummation of a Qualified Public Offering.

2.4 Filing of Reports Under the Exchange Act.

(a) The Corporation shall give prompt notice to the holders of Preferred Stock of (i) the filing of any registration statement (an “Exchange Act Registration Statement”) pursuant to the Exchange Act, relating to any class of equity securities of the Corporation, (ii) the effectiveness of such Exchange Act Registration Statement, and (iii) the number of shares of such class of equity securities outstanding, as reported in such Exchange Act Registration Statement, in order to enable the Stockholders to comply with any reporting requirements under the Exchange Act or the Securities Act. Upon the written request of the Majority Investors, the Corporation shall, at any time after the Corporation has already registered shares of Common Stock under the Securities Act file an Exchange Act Registration Statement relating to any class of equity securities of the Corporation or issuable upon conversion or exercise of any class of debt or equity securities or warrants or options of the Corporation then held by the Series A-1 Stockholders, whether or not the class of equity securities with respect to which such request is made shall be held by the number of persons which would require the filing of a registration statement under Section 12(g)(I) of the Exchange Act.

100

(b) If the Corporation shall have filed an Exchange Act Registration Statement or a registration statement (including an offering circular under Regulation A promulgated under the Securities Act) pursuant to the requirements of the Securities Act, which shall have become effective (and in any event, at all times following the initial public offering of any of the securities of the Corporation), then the Corporation shall comply with all other reporting requirements of the Exchange Act (whether or not it shall be required to do so) and shall comply with all other public information reporting requirements of the Commission as a condition to the availability of an exemption from the Securities Act for the sale of any of the Restricted Stock by any holder of Restricted Stock or the sale of any of the Series A-1 Stock by any holder of Series A-1 Stock (including any such exemption pursuant to Rule 144 or Rule 144A thereof, as amended from time to time, or any successor rule thereto or otherwise). The Corporation shall cooperate with each holder of Registrable Securities in supplying such information as may be necessary for such holder to complete and file any information reporting forms presently or hereafter required by the Commission as a condition to the availability of an exemption from the Securities Act (under Rule 144 or Rule 144A thereunder or otherwise) for the sale of any Registrable Securities.

2.5 Directors’ & Officers’ Insurance. The Corporation shall continue to maintain a directors’ and officers’ liability insurance policy covering all directors, observers and executive officers of the Corporation.

2.6 Properties and Business Insurance. The Corporation shall continue to maintain from responsible and reputable insurance companies or associations valid policies of insurance against such casualties, contingencies and other risks and hazards and of such types and in such amounts as is customary for similarly situated businesses.

2.7 Preservation of Corporate Existence. The Corporation shall preserve and maintain its corporate existence, rights, franchises and privileges in the jurisdiction of its incorporation, and qualify and remain qualified as a foreign corporation in each jurisdiction in which (i) such qualification is necessary or desirable in view of its business and operations or the ownership or lease of its properties or (ii) the failure to so qualify would have a material adverse effect on the business, properties, assets or condition (financial or otherwise) of the Corporation.

2.8 Compliance with Laws. The Corporation shall comply with all applicable laws, rules, regulations, requirements and orders of the United States or any applicable foreign jurisdiction in the conduct of its business including, without limitation, all labor, employment, wage and hour, health and safety, environmental, health insurance, health information security, privacy, data protection and data transfer laws, and shall adopt and monitor policies and procedures designed to comply with all such applicable laws, rules, regulations and orders, except where noncompliance would not have a material adverse effect on the business, properties, assets or condition (financial or otherwise) of the Corporation.

2.9 Payment of Taxes. The Corporation will pay and discharge all lawful Taxes (as defined below) before such Taxes shall become in default and all lawful claims for labor, materials and supplies which, if not paid when due, might become a lien or charge upon its property or any part thereof; provided, however, that the Corporation shall not be required to pay and discharge any such Tax, assessment, charge, levy or claim so long as the validity thereof is being contested by or for the Corporation in good faith by appropriate proceedings and an adequate reserve therefore has been established on its books. The term “Tax” (and, with correlative meaning, “Taxes”) means all United States federal, state and local, and all foreign, income, profits, franchise, gross receipts, payroll, transfer, sales, employment, use, property, excise, value added, ad valorem, estimated, stamp, alternative or add-on minimum, recapture, environmental, withholding and any other taxes, charges, duties, impositions or

Any grants of capital stock or options to employees, officers, directors or consultants of the Corporation and its Subsidiaries shall be made pursuant to the Plan.

2.11 No Further Pay-to-Play Provisions. The Corporation hereby covenants and agrees that at no time after the date of this Agreement, without the prior written consent of each of Wellcome, one member of the HCV Group, one member of the MPM Group, one member of the Brookside Group, one member of the BB Bio Group, and one member of the Oxford/Saints Group, shall it enter into any agreement or amend the Certificate to implement terms that would automatically convert Preferred Shares into shares of Common Stock, or impose any other penalty on the holder of Preferred Shares, solely because the holders of such Preferred Shares fail to participate at any level in a transaction pursuant to which the Corporation raises funds through the issuance of debt or equity securities (other than any Closing contemplated by the Stock Purchase Agreement).

2.12 Confidentiality, Assignment of Inventions and Non-Competition Agreements for Key Employees. The Corporation shall cause each person who becomes an employee of or a consultant to the Corporation subsequent to the date hereof, and who shall have or be proposed to have access to confidential or proprietary information of the Corporation, to execute a confidentiality, assignment of inventions, and non-competition agreement in form and substance attached hereto as Exhibit A or otherwise approved by the Board prior to the commencement of such person’s employment by the Corporation in such capacity.

2.13 Duration of Section. Sections 2.5 through 2.12 and the rights and obligations of the parties hereunder shall automatically terminate on the earlier of (i) the consummation of an Event of Sale (as defined in the Certificate) or (ii) the automatic conversion of all of the Preferred Stock of the Corporation pursuant to the terms and conditions of the Certificate upon the listing, or the admitting for trading, of the Common Stock on a national securities exchange.

The Series A-1 Preferred Stock, Series A-2 Preferred Stock, the Series A-3 Preferred Stock and the Restricted Stock shall not be transferable, except upon the conditions specified in this Section 3, which conditions are intended solely to ensure compliance with the provisions of the Securities Act in respect of the Transfer thereof. In addition, no Series A-1 Preferred Stock, Series A-2 Preferred Stock, the Series A-3 Preferred Stock or Restricted Stock shall be transferred unless, as conditions precedent to such transfer, the transferee thereof agrees in writing to be bound by the obligations of the transferring Stockholder hereunder.

3.2 Restrictive Legend. Each certificate evidencing any Series A-1 Preferred Stock, Series A-2 Preferred Stock, Series A-3 Preferred Stock and Restricted Stock and each certificate evidencing any such securities issued to subsequent transferees of any Series A-1 Preferred Stock, Series A-2 Preferred Stock, Series A-3 Preferred Stock and Restricted Stock shall (unless otherwise permitted by the provisions of Section 3.3 or 3.10 hereof) be stamped or otherwise imprinted with a legend in substantially the following form:

102

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAW. THE SECURITIES MAY NOT BE PLEDGED, HYPOTHECATED, SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAW OR AN EXEMPTION THEREFROM UNDER SUCH ACT OR LAW.

3.3 Notice of Transfer. By acceptance of any Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock, the holder thereof agrees to give prior written notice to the Corporation of such holder’s intention to effect any Transfer and to comply in all other respects with the provisions of this Section 3.3. Each such notice shall describe the manner and circumstances of the proposed Transfer and shall be accompanied by: (a) the written opinion of counsel for the holder of such Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock, or, at such holder’s option, a representation letter of such holder, addressed to the Corporation (which opinion and counsel, or representation letter, as the case may be, shall be reasonably acceptable to the Corporation), as to whether, in the case of a written opinion, in the opinion of such counsel such proposed Transfer involves a transaction requiring registration of such Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock under the Securities Act and applicable state securities laws or an exemption thereunder is available, or, in the case of a representation letter, such letter sets forth a factual basis for concluding that such proposed transfer involves a transaction requiring registration of such Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock under the Securities Act and applicable state securities laws or that an exemption thereunder is available, or (b) if such registration is required and if the provisions of Section 3.4 hereof are applicable, a written request addressed to the Corporation by the holder of such Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock, describing in detail the proposed method of disposition and requesting the Corporation to effect the registration of such Registrable Shares pursuant to the terms and provisions of Section 3.4 hereof; provided, however, that (y) in the case of a Transfer by a holder to a member of such holder’s Group, no such opinion of counsel or representation letter of the holder shall be necessary, provided that the transferee agrees in writing to be subject to Sections 3.1, 3.2, 3.3, 3.10 hereof to the same extent as if such transferee were originally a signatory to this Agreement, and (z) in the case of any holder of Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock that is a partnership, no such opinion of counsel or representation letter of the holder shall be necessary for a Transfer by such holder to a partner of such holder, or a retired partner of such holder who retires after the date hereof, or the estate of any such partner or retired partner if, with respect to such Transfer by a partnership, (i) such Transfer is made in accordance with the partnership agreement of such partnership, and (ii) the transferee agrees in writing to be subject to the terms of Sections 3.1, 3.2, 3.3, 3.10 hereof to the same extent as if such transferee were originally a signatory to this Agreement. If in an opinion of counsel or as reasonably concluded from the facts set forth in the representation letter of the holder (which opinion and counsel or representation letter, as the case may be, shall be reasonably acceptable to the Corporation), the proposed Transfer may be effected without registration under the Securities Act and any applicable state securities laws or “blue sky” laws, then the holder of Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock shall thereupon be entitled to effect such Transfer in accordance with the terms of the notice delivered by it to the Corporation. Each certificate or other instrument evidencing the securities issued upon such Transfer (and each certificate or other instrument evidencing any such securities not Transferred) shall bear the legend set forth in Section 3.2 hereof unless: (a) in such opinion of such counsel or as can be concluded from the representation letter of such holder (which opinion and counsel or representation letter shall be reasonably acceptable to the

103

Corporation) the registration of future Transfers is not required by the applicable provisions of the Securities Act and state securities laws, or (b) the Corporation shall have waived the requirement of such legend; provided, however, that such legend shall not be required on any certificate or other instrument evidencing the securities issued upon such Transfer in the event such transfer shall be made in compliance with the requirements of Rule 144 (as amended from time to time or any similar or successor rule) promulgated under the Securities Act. The holder of Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock shall not effect any Transfer until such opinion of counsel or representation letter of such holder has been given to and accepted by the Corporation (unless waived by the Corporation) or, if applicable, until registration of the Registrable Shares involved in the above-mentioned request has become effective under the Securities Act. In the event that an opinion of counsel is required by the registrar or transfer agent of the Corporation to effect a transfer of Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock in the future, the Corporation shall seek and obtain such opinion from its counsel, and the holder of such Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock shall provide such reasonable assistance as is requested by the Corporation (other than the furnishing of an opinion of counsel) to satisfy the requirements of the registrar or transfer agent to effectuate such transfer. Notwithstanding anything to the contrary herein, the provisions of this Section 3.3 and of Sections 3.1 and 3.2 shall not apply, and shall be deemed of no force or effect, with respect to shares of capital stock of the Corporation that are subject to a re-sale registration statement under the Securities Act, provided that such registration statement has been declared, and continues to remain, effective by the Commission.

3.4 Registration Rights.

(a) Shelf Registration.

(i) On or prior to the Filing Date, the Corporation shall prepare and file with the Commission a Registration Statement covering the resale of all of the Registrable Shares for an offering to be made on a continuous basis pursuant to Rule 415. The Registration Statement shall be on Form S-1 or another appropriate form in accordance herewith and shall contain (unless otherwise directed by Holders of at least 85% of the then outstanding Registrable Shares) substantially the “Plan of Distribution” attached hereto as Annex A. Subject to the terms of this Agreement, the Corporation shall use its reasonable best efforts to cause such Registration Statement to be declared effective under the Securities Act as promptly as possible after the filing thereof, but in any event on or prior to the Effectiveness Date, and shall use its reasonable best efforts to keep the Registration Statement continuously effective (whether on Form S-1 or amended to Form S-3 or another appropriate form in accordance herewith) under the Securities Act until all Registrable Shares have been sold, or may be sold without volume restrictions pursuant to Rule 144, as determined by the counsel to the Corporation pursuant to a written opinion letter to such effect, addressed and acceptable to the transfer agent of the Corporation and the affected Holders (the “Effectiveness Period”). The Corporation shall telephonically request effectiveness of the Registration Statement as of 5:00 p.m. New York City time on a day during which the public markets are open for trading stocks (a “Trading Day”). The Corporation shall immediately notify the Holders via facsimile or by e-mail delivery of a “.pdf” format data file of the effectiveness of the Registration Statement on the same Trading Day that the Corporation telephonically confirms effectiveness with the Commission, which shall be the date requested for effectiveness of the Registration Statement. The Corporation shall, by 9:30 a.m. New York City time on the Trading Day after the Effective Date, file a final Prospectus with the Commission as required by Rule 424. Failure to so notify the Holder within 1 Trading Day of such notification of effectiveness or failure to file a final Prospectus as foresaid shall be deemed an Event under Section 3.4(b).

104

(ii) If: (A) the Registration Statement is not filed on or prior to the Filing Date or has not been declared effective by the Commission by the Effectiveness Date, or (B) the Corporation fails to file with the Commission a request for acceleration in accordance with Rule 461 promulgated under the Securities Act, within 5 Trading Days of the date that the Corporation is notified (orally or in writing, whichever is earlier) by the Commission that a Registration Statement will not be “reviewed” or not be subject to further review, or (C) prior to the Effectiveness Date of a Registration Statement, the Corporation fails to file a pre-effective amendment and otherwise respond in writing to comments made by the Commission in respect of such Registration Statement within 14 calendar days after the receipt of comments by or notice from the Commission that such amendment is required in order for such Registration Statement to be declared effective, or (D) after the Effectiveness Date of a Registration Statement, such Registration Statement ceases for any reason to remain continuously effective as to all Registrable Securities included in such Registration Statement, or the Holders are otherwise not permitted to utilize the Prospectus therein to resell such Registrable Securities, for more than 20 consecutive calendar days or more than an aggregate of 40 calendar days during any 12-month period (which need not be consecutive calendar days) (any such failure or breach being referred to as an “Event”, and for purposes of clause (A) the date on which such Event occurs, or for purposes of clause (B) the date on which such 5 Trading Day period is exceeded, or for purposes of clause (C) the date which such 14 calendar day period is exceeded, or for purposes of clause (D) the date on which such 20 or 40 calendar day period, as applicable, is exceeded being referred to as an “Event Date”), then, in addition to any other rights the Holders may have hereunder or under applicable law, on each such Event Date and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable Event is cured, the Corporation shall pay to each Holder an amount in cash, as partial liquidated damages and not as a penalty, equal to 1% of the aggregate purchase price paid by such Holder pursuant to the Stock Purchase Agreement for any Registrable Securities then held by such Holder. The parties agree that the maximum aggregate liquidated damages payable to a Holder under this Agreement shall be sixteen percent (16%) of the aggregate Purchase Price (as defined in the Stock Purchase Agreement) paid by such Holder pursuant to the Stock Purchase Agreement. If the Corporation fails to pay any partial liquidated damages pursuant to this Section 3.4(b) in full within seven days after the date payable, the Corporation will pay interest thereon at a rate of ten percent (10%) per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the Holder, accruing daily from the date such partial liquidated damages are due until such amounts, plus all such interest thereon, are paid in full. The partial liquidated damages pursuant to the terms hereof shall apply on a daily pro-rata basis for any portion of a month prior to the cure of an Event.

(iii) In the event that the Corporation is unable for any reason to include in the Registration Statement required to be filed under Section 3.4(a)(i) all of the Registrable Securities, then the Corporation shall use its reasonable best efforts to file and cause to be declared effective additional Registration Statements, in order to uphold its obligations under Section 3.4(a)(i), as promptly as practicable. If not all Registrable Securities may be included in any one Registration Statement, then the Registrable Securities to be included shall be allocated among Holders of such Registrable Securities on a pro rata basis based on the total number of Registrable Securities held by all Holders that have not been included in a Registration Statement.

(b) Registration Procedures. In connection with the Corporation’s registration obligations hereunder, the Corporation shall:

(i) Not less than seven Trading Days prior to the filing of any Registration Statement and not less than two Trading Days prior to the filing of any related Prospectus or any amendment or supplement thereto, (A) furnish to each Holder copies of all such documents proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will be subject to the review of such Holders, and (B) cause its officers and directors, counsel and

105

independent certified public accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of respective counsel to each Holder, to conduct a reasonable investigation within the meaning of the Securities Act; and not file a Registration Statement or any such Prospectus or any amendments or supplements thereto to which the Holders of 67% of the Registrable Securities shall reasonably object in good faith, provided that the Corporation is notified of such objection in writing no later than 5 Trading Days after the Holders have been so furnished copies of a Registration Statement or 1 Trading Day after the Holders have been so furnished copies of any related Prospectus or amendments or supplements thereto. Each Holder agrees to furnish to the Corporation a completed questionnaire in the form attached to this Agreement as Annex B or other form reasonably acceptable to the Corporation (a “Selling Stockholder Questionnaire”) not less than 2 Trading Days prior to the Filing Date or by the end of the 4th Trading Day following the date on which such Holder receives draft materials in accordance with this Section. During any periods that the Corporation is unable to meet its obligations hereunder with respect to the registration of the Registrable Securities because the Holders of 67% of the Registrable Securities exercise their rights under this section to object to the filing of a Registration Statement, any liquidated damages that are accruing, at such time shall be tolled and any Event that may otherwise occur because of the exercise of such rights or such delay shall be suspended, until the Holders of 67% of the Registrable Securities no longer object to the filing of such Registration Statement (provided that such tolling shall only occur if the Corporation uses commercially reasonable efforts to resolve such objection). If any Holder fails to furnish its Selling Stockholder Questionnaire related to a particular Registration Statement not less than 2 Trading Days prior to the Filing Date or by the end of the 4th Trading Day following the date on which such Holder receives draft materials in accordance with this Section, any liquidated damages that are accruing, as well as any other rights of such Holder under this Agreement with regard to such Registration Statement, including without limitation, the right to include such Holder’s Registrable Securities in such Registration Statement, shall be tolled as to such Holder until such information is received by the Corporation; provided, however, that the Corporation shall use commercially reasonable efforts to include such Registrable Securities in such Registration Statement or the next most available Registration Statement as soon as possible after such information is furnished to the Corporation.

(ii) (A) Prepare and file with the Commission such amendments, including post-effective amendments, to a Registration Statement and the Prospectus used in connection therewith as may be necessary to keep a Registration Statement continuously effective as to the applicable Registrable Securities for the Effectiveness Period and prepare and file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (B) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and as so supplemented or amended to be filed pursuant to Rule 424; (C) respond as promptly as reasonably possible to any comments received from the Commission with respect to a Registration Statement or any amendment thereto and provide as promptly as reasonably possible to the Holders true and complete copies of all correspondence from and to the Commission relating to a Registration Statement (provided that the Corporation may excise any information contained therein which would constitute material non-public information as to any Holder which has not executed a confidentiality agreement with the Corporation); and (D) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by a Registration Statement during the applicable period in accordance (subject to the terms of this Agreement) with the intended methods of disposition by the Holders thereof set forth in such Registration Statement as so amended or in such Prospectus as so supplemented.

(iii) If during the Effectiveness Period, the number of Registrable Securities at any time exceeds 100% of the number of shares of Common Stock then registered in a Registration Statement, file as soon as reasonably practicable an additional Registration Statement covering the resale by the Holders of not less than the number of such Registrable Securities.

(iv) Notify the Holders of Registrable Securities to be sold (which notice shall, pursuant to clauses (C) through (F) hereof, be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly as reasonably possible (and, in the case of (A)(1) below, not less than 1 Trading Day prior to such filing, in the case of (C) and (D) below, not more than 1 Trading Day after such issuance or receipt and, in the case of (E) below, not less than 3 Trading Days prior to the financial statements in any Registration Statement becoming ineligible for inclusion therein) and (if requested by any such Person) confirm such notice in writing no later than 1 Trading Day following the day (A)(1) when a Prospectus or any Prospectus supplement or post-effective amendment to a Registration Statement is proposed to be filed; (2) when the Commission notifies the Corporation whether there will be a “review” of such Registration Statement and whenever the Commission comments in writing on such Registration Statement (in which case the Corporation shall provide true and complete copies thereof and all written responses thereto to each of the Holders that pertain to the Holders as a selling stockholder or to the Plan of Distribution, but not information which the Corporation believes would constitute material and non-public information); and (3) with respect to a Registration Statement or any post-effective amendment, when the same has become effective; (B) of any request by the Commission or any other federal or state governmental authority for amendments or supplements to a Registration Statement or Prospectus or for additional information; (C) of the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (D) of the receipt by the Corporation of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; (E) of the occurrence of any event or passage of time that makes the financial statements included in a Registration Statement ineligible for inclusion therein or any statement made in a Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to a Registration Statement, Prospectus or other documents so that, in the case of a Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; and (F) the occurrence or existence of any pending corporate development with respect to the Corporation that the Corporation believes may be material and that, in the good faith determination of the Corporation, based on the advice of counsel, makes it not in the best interest of the Corporation to allow continued availability of a Registration Statement or Prospectus, provided that any and all of such information shall remain confidential to each Holder until such information otherwise becomes public, unless disclosure by a Holder is required by law; provided, further, that notwithstanding each Holder’s agreement to keep such information confidential, the Holders make no acknowledgement that any such information is material, non-public information.

(v) Use its reasonable best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (A) any order suspending the effectiveness of a Registration Statement, or (B) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment.

(vi) If requested by a Holder, furnish to such Holder, without charge (A) at least one conformed copy of each such Registration Statement and each amendment thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference to the extent requested by such Person, and all exhibits to the extent requested by such Person (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the Commission, and (B) during the Effectiveness Period, as many copies of the Prospectus included in the Registration Statement and any amendment or supplement thereto as such

107

Holder may reasonably request; provided, however, that the Corporation shall have no obligation to provide any document pursuant to this clause that is available on the Commission’s XXXXX system.

(vii) Subject to the terms of this Agreement, consent to the use of each Prospectus and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto, except after the giving of any notice pursuant to Section 3.4(b)(iv).

(viii) Effect a filing with respect to the public offering contemplated by the Registration Statement (an “Issuer Filing”) with the Financial Industry Regulatory Authority (“FINRA”) Corporate Financing Department pursuant to FINRA Rule 5110 within 1 Trading Day of the date that the Registration Statement is first filed with the Commission and pay the filing fee required by such Issuer Filing; and use commercially reasonable efforts to pursue the Issuer Filing until FINRA issues a letter confirming that it does not object to the terms of the offering contemplated by the Registration Statement.

(ix) Prior to any resale of Registrable Securities by a Holder, use its reasonable best efforts to register or qualify or cooperate with the selling Holders in connection with the registration or qualification (or exemption from the registration or qualification) of such Registrable Securities for the resale by the Holder under the securities or blue sky laws of such jurisdictions within the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or things reasonably necessary to enable the disposition in such jurisdictions of the Registrable Securities covered by a Registration Statement; provided, that the Corporation shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified, subject the Corporation to any material tax in any such jurisdiction where it is not then so subject or file a general consent to service of process in any such jurisdiction.

(x) If requested by the Holders, cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the extent permitted by the Stock Purchase Agreement, of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holders may request. In connection therewith, if required by the Corporation’s transfer agent, the Corporation shall promptly after the effectiveness of a Registration Statement cause an opinion of counsel as to the effectiveness of the Registration Statement to be delivered to and maintained with the transfer agent, together with any other authorizations, certificates and directions required by the transfer agent, which authorize and direct the transfer agent to issue such Registrable Securities without legend upon sale by the holder of such shares of Registrable Securities under the Registration Statement.

(xi) Upon the occurrence of any event contemplated by this Section 3.4(b), as promptly as reasonably possible under the circumstances taking into account the Corporation’s good faith assessment of any adverse consequences to the Corporation and its stockholders of the premature disclosure of such event, prepare a supplement or amendment, including a post-effective amendment, to a Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither a Registration Statement nor Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Corporation notifies and instructs the Holders in accordance with clauses (iii) through (vi) of Section 3.4(b)(iv) above to suspend the use of any Prospectus until the requisite changes to such

108

Prospectus have been made, then the Holders shall suspend use of such Prospectus; use its reasonable best efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable; and be entitled to exercise its right under this Section 3.4(b)(xi) to suspend the availability of a Registration Statement and Prospectus, subject to the payment of partial liquidated damages pursuant to Section 3.4(a)(ii), for a period not to exceed 40 calendar days (which need not be consecutive days) in any 12 month period.

(xii) Comply with all applicable rules and regulations of the Commission.

(c) The Corporation may require each selling Holder to furnish to the Corporation a certified statement as to the number of shares of Common Stock beneficially owned by such Holder and any affiliate thereof and as to any FINRA affiliations and, if required by the Commission, of any natural persons that have voting and dispositive control over the Registrable Securities. During any periods that the Corporation is unable to meet its obligations hereunder with respect to the registration of the Registrable Securities solely because any Holder fails to furnish such information within 3 Trading Days of the Corporation’s request, any liquidated damages that are accruing at such time as to such Holder only, as well as any other rights of such Holder under this Agreement, including without limitation, the right to include such Holder’s Registrable Securities in a Registration Statement shall be tolled and any Event that may otherwise occur solely because of such delay shall be suspended as to such Holder only, until such information is delivered to the Corporation; provided, however, that the Corporation shall use commercially reasonable efforts to include such Registrable Securities in such Registration Statement or the next most available Registration Statement as soon as possible after such information is furnished to the Corporation.

3.5 Piggyback Registration.

(a) Each time that the Corporation proposes for any reason to register any of its securities under the Securities Act, other than pursuant to a registration statement on Form X-0, Xxxx X-0 or Form S-1 or similar or successor forms, but in regard to Form S-1 only in connection with the initial public offering of the Corporation’s Common Stock (collectively, “Excluded Forms”), the Corporation shall promptly give written notice of such proposed registration to all holders of Registrable Securities, which notice shall also constitute an offer to such holders to request inclusion of any Registrable Shares in the proposed registration.

(b) Each holder of Registrable Securities shall have 30 days from the receipt of such notice to deliver to the Corporation a written request specifying the number of Registrable Shares such holder intends to sell and the holder’s intended method of disposition.

(c) In the event that the proposed registration by the Corporation is, in whole or in part, an underwritten public offering of securities of the Corporation, any request under Section 3.5(b) may specify that the Registrable Shares be included in the underwriting (i) on the same terms and conditions as the shares of Common Stock, if any, otherwise being sold through underwriters under such registration, or (ii) on terms and conditions comparable to those normally applicable to offerings of common stock in reasonably similar circumstances in the event that no shares of Common Stock other than Registrable Shares are being sold through underwriters under such registration.

109

(d) Upon receipt of a written request pursuant to Section 3.5(b), the Corporation shall promptly use its best efforts to cause all such Registrable Shares to be registered under the Securities Act, to the extent required to permit sale or disposition as set forth in the written request.

(e) Notwithstanding the foregoing, if the managing underwriter of any such proposed registration determines and advises in writing that the inclusion of all Registrable Shares proposed to be included in the underwritten public offering, together with any other issued and outstanding shares of Common Stock proposed to be included therein by holders other than the holders of Registrable Securities (such other shares hereinafter collectively referred to as the “Other Shares”) would interfere with the successful marketing of the Corporation’s securities, then the total number of such securities proposed to be included in such underwritten public offering shall be reduced, (i) first by the shares requested to be included in such registration by the holders of Other Shares, (ii) second, if necessary by all Registrable Securities which are not Series A-2 Registrable Securities, Series A-3 Registrable Securities or Series A-1 Registrable Securities, and (iii) third, if necessary, (A) one-half (1/2) by the securities proposed to be issued by the Corporation, and (B) one-half (1/2) by the holders of Series A-2 Registrable Shares, Series A-3 Registrable Shares and/or Series A-1 Registrable Shares proposed to be included in such registration by the holders thereof, on a pro rata basis calculated based upon the number of Registrable Shares, Series A-2 Registrable Shares, Series A-3 Registrable Shares or Series A-1 Registrable Shares sought to be registered by each such holder; provided, that the aggregate number of securities proposed to be included in such registration by the holders of Series A-2 Registrable Shares, Series A-3 Registrable Shares and/or Series A-1 Registrable Shares shall only be reduced hereunder if and to the extent that such securities exceed twenty-five percent (25%) of the aggregate number of securities included in such registration. The shares of Common Stock that are excluded from the underwritten public offering pursuant to the preceding sentence shall be withheld from the market by the holders thereof for a period, not to exceed 90 days from the closing of such underwritten public offering, that the managing underwriter reasonably determines as necessary in order to effect such underwritten public offering.

3.6 Registrations on Form S-3. At such time as the Registration Statement contemplated by Section 3.4 shall no longer be effective, each holder of Registrable Securities shall have the right to request in writing an unlimited number of registrations on Form S-3. Each such request by a holder shall: (a) specify the number of Registrable Shares which the holder intends to sell or dispose of, (b) state the intended method by which the holder intends to sell or dispose of such Registrable Shares, and (c) request registration of Registrable Shares having a proposed aggregate offering price of at least $1,000,000. Upon receipt of an adequate request pursuant to this Section 3.6, the Corporation shall use its best efforts to effect such registration or registrations on Form S-3.

3.7 Preparation and Filing. If and whenever the Corporation is under an obligation pursuant to the provisions of Sections 3.5 and/or 3.6 to use its best efforts to effect the registration of any Registrable Shares, the Corporation shall, as expeditiously as practicable:

(a) prepare and file with the Commission a registration statement with respect to such securities and use its best efforts to cause such registration statement to become and remain effective in accordance with Section 3.7(b) hereof;

(b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective until the earlier of (i) the sale of all Registrable Shares covered thereby or (ii) nine months from the date such registration statement first becomes effective, and to comply with the provisions of the Securities Act with respect to the sale or other disposition of all Registrable Shares covered by such registration statement;

110

(c) furnish to each holder whose Registrable Shares are being registered pursuant to this Section 3 such number of copies of any summary prospectus or other prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as such holder may reasonably request in order to facilitate the public sale or other disposition of such Registrable Shares;

(d) use its best efforts to register or qualify the Registrable Shares covered by such registration statement under the securities or blue sky laws of such jurisdictions as each holder whose Registrable Shares are being registered pursuant to this Section 3 shall reasonably request, and do any and all other acts or things which may be necessary or advisable to enable such holder to consummate the public sale or other disposition in such jurisdictions of such Registrable Shares; provided, however, that the Corporation shall not be required to consent to general service of process for all purposes in any jurisdiction where it is not then subject to process, qualify to do business as a foreign corporation where it would not be otherwise required to qualify or submit to liability for state or local taxes where it is not otherwise liable for such taxes;

(e) at any time when a prospectus covered by such registration statement and relating thereto is required to be delivered under the Securities Act within the appropriate period mentioned in Section 3.7(b) hereof, notify each holder whose Registrable Shares are being registered pursuant to this Section 3 of the happening of any event as a result of which the prospectus included in such registration, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and, at the request of such holder, prepare, file and furnish to such holder a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing;

(f) if the Corporation has delivered preliminary or final prospectuses to the holders of Registrable Shares that are being registered pursuant to this Section 3 and after having done so the prospectus is amended to comply with the requirements of the Securities Act, the Corporation shall promptly notify such holders and, if requested, such holders shall immediately cease making offers of Registrable Shares and return all prospectuses to the Corporation. The Corporation shall promptly provide such holders with revised prospectuses and, following receipt of the revised prospectuses, such holders shall be free to resume making offers of the Registrable Shares; and

(g) furnish, at the request of any holder whose Registrable Shares are being registered pursuant to this Section 3, on the date that such Registrable Shares are delivered to the underwriters for sale in connection with a registration pursuant to this Section 3 if such securities are being sold through underwriters, or on the date that the registration statement with respect to such securities becomes effective if such securities are not being sold through underwriters, (i) an opinion, dated such date, of the counsel representing the Corporation for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the holder or holders making such request, and (ii) a letter dated such date, from the independent certified public accountants of the Corporation, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the holder or holders making such request.

111

all expenses incident to filing with the FINRA), fees and expenses of complying with the securities and blue sky laws of all such jurisdictions in which the Registrable Shares are proposed to be offered and sold, printing expenses and fees and disbursements of counsel (including with respect to each registration effected pursuant to Sections 3.4, 3.5 and 3.6, the reasonable fees and disbursements of a counsel for the holders of Registrable Shares that are being registered pursuant to this Section 3, such counsel for the holders of Registrable Shares shall be designated by a vote of a majority of the holders of Registrable Shares to be included in such registration, determined in accordance with Article III, Section A.6(a) of the Certificate); provided, however, that all underwriting discounts and selling commissions applicable to the Registrable Shares covered by registrations effected pursuant to Section 3.4, 3.5 or 3.6 hereof shall be borne by the seller or sellers thereof, in proportion to the number of Registrable Shares sold by each such seller or sellers.

3.9 Indemnification.

(a) In the event of any registration of any Registrable Shares under the Securities Act pursuant to this Section 3 or registration or qualification of any Registrable Shares pursuant to Section 3.7(d) hereof, the Corporation shall indemnify and hold harmless the seller of such shares, each underwriter of such shares, if any, each broker or any other person acting on behalf of such seller and each other person, if any, who controls any of the foregoing persons, within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which any of the foregoing persons may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any registration statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, or any document incident to registration or qualification of any Registrable Shares pursuant to Section 3.7(d) hereof or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or, with respect to any prospectus, necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or any violation by the Corporation of the Securities Act or any state securities or blue sky laws applicable to the Corporation and relating to action or inaction required of the Corporation in connection with such registration or qualification under the Securities Act or such state securities or blue sky laws. The Corporation shall reimburse on demand such seller, underwriter, broker or other person acting on behalf of such seller and each such controlling person for any legal or any other expenses reasonably incurred by any of them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Corporation shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in said registration statement, preliminary or final prospectus or amendment or supplement thereto or any document incident to registration or qualification of any Registrable Shares pursuant to Section 3.7(d) hereof, in reliance upon and in conformity with written information furnished to the Corporation by such seller, underwriter, broker, other person or controlling person specifically for use in the preparation hereof.

(b) Before Registrable Shares held by any prospective seller shall be included in any registration pursuant to this Section 3, such prospective seller and any underwriter acting on its behalf shall have agreed to indemnify and hold harmless (in the same manner and to the same extent as set forth in paragraph (a)) the Corporation, each director of the Corporation, each officer of the Corporation who signs such registration statement and any person who controls the Corporation within the meaning of the Securities Act, with respect to any untrue statement or omission from such registration statement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, if such untrue statement or omission was made in reliance upon and in conformity

112

with written information furnished to the Corporation through an instrument duly executed by such seller or such underwriter specifically for use in the preparation of such registration statement, preliminary prospectus, final prospectus or amendment or supplement; provided, however, that the maximum amount of liability in respect of such indemnification shall be limited, in the case of each prospective seller, to an amount equal to the net proceeds actually received by such prospective seller from the sale of Registrable Shares effected pursuant to such registration.

(c) Promptly after receipt by an indemnified party of notice of the commencement of any action involving a claim referred to in Section 3.9(a) or (b) hereof, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 3.9, give written notice to the latter of the commencement of such action. In case any such action is brought against an indemnified party, the indemnifying party will be entitled to participate in and to assume the defense thereof jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and, after notice to such indemnified party from the indemnifying party of its election to assume the defense thereof, the indemnifying party shall be responsible for any legal or other expenses subsequently incurred by such indemnifying party in connection with the defense thereof; provided, however, that, if any indemnified party shall have reasonably concluded that there may be one or more legal defenses available to such indemnified party which are different from or additional to those available to the indemnifying party, or that such claim or litigation involves or could have an effect upon matters beyond the scope of the indemnity agreement provided in this Section 3.9, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party, and such indemnifying party shall reimburse such indemnified party and any person controlling such indemnified party for the fees and expenses of counsel retained by the indemnified party which are reasonably related to the matters covered by the indemnity agreement provided in this Section 3.9. The indemnifying party shall not make any settlement of any claims in respect of which it is obligated to indemnify an indemnified party or parties hereunder, without the written consent of the indemnified party or parties, which consent shall not be unreasonably withheld.

(d) In order to provide for just and equitable contribution to joint liability under the Securities Act, in any case in which either (i) any holder of Registrable Shares exercising rights under this Agreement, or any controlling person of any such holder, makes a claim for indemnification pursuant to this Section 3.9, but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 3.9 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any such holder or any such controlling person in circumstances for which indemnification is provided under this Section 3.9; then, in each such case, the Corporation and such holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject as is appropriate to reflect the relative fault of the Corporation and such holder in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, it being understood that the parties acknowledge that the overriding equitable consideration to be given effect in connection with this provision is the ability of one party or the other to correct the statement or omission which resulted in such losses, claims, damages or liabilities, and that it would not be just and equitable if contribution pursuant hereto were to be determined by pro rata allocation or by any other method of allocation which does not take into consideration the foregoing equitable considerations. Notwithstanding the foregoing, (i) no such holder will be required to contribute any amount in excess of the proceeds to it of all Registrable Shares sold by it pursuant to such registration statement, and (ii) no person or entity guilty of fraudulent misrepresentation, within the meaning of Section 11(f) of the Securities Act, shall be entitled to contribution from any person or entity who is not guilty of such fraudulent misrepresentation.

113

(e) Notwithstanding any of the foregoing, if, in connection with an underwritten public offering of any Registrable Shares, the Corporation, the holders of such Registrable Shares and the underwriters enter into an underwriting or purchase agreement relating to such offering which contains provisions covering indemnification among the parties, then the indemnification provision of this Section 3.9 shall be deemed inoperative for purposes of such offering.

3.10 Removal of Legends, Etc. Notwithstanding the foregoing provisions of this Section 3, the restrictions imposed by this Section 3 upon the transferability of any Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock shall cease and terminate when (a) any such Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock are sold or otherwise disposed of in accordance with the intended method of disposition by the seller or sellers thereof set forth in a registration statement or such other method contemplated by Section 3.3 hereof that does not require that the securities transferred bear the legend set forth in Section 3.2 hereof, including a Transfer pursuant to Rule 144 or a successor rule thereof (as amended from time to lime), or (b) the holder of Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock has met the requirements for transfer of such Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock pursuant to subparagraph (b)(1) of Rule 144 or a successor rule thereof (as amended from time to time) promulgated by the Commission under the Securities Act. Whenever the restrictions imposed by this Section 3 have terminated, a holder of a certificate for Restricted Stock, Series A-1 Preferred Stock, Series A-2 Preferred Stock or Series A-3 Preferred Stock as to which such restrictions have terminated shall be entitled to receive from the Corporation, without expense, a new certificate not bearing the restrictive legend set forth in Section 3.2 hereof and not containing any other reference to the restrictions imposed by this Section 3. Notwithstanding the above, nothing herein shall limit the restrictions imposed upon transfer of the Restricted Securities pursuant to Section 8 hereof nor the imposition of the legend provided for therein.

Subject to the requirements of Section 3 hereof, this Agreement and the rights and duties of the Series A-1 Stockholder, Series A-2 Stockholder and Series A-3 Stockholder set forth herein may be freely assigned, in whole or in part, by each Series A-1 Stockholder, Series A-2 Stockholder and Series A-3 Stockholder to any member of their respective Group, provided such transferee is an “affiliate” of such Series A-1 Stockholder, Series A-2 Stockholder or Series A-3 Stockholder, as the case may be, as such term is defined under Rule 501 of the Securities Act (it being recognized and agreed that each member of the Oxford/Saints Group shall be deemed to be “affiliates” of each other for this purpose). Any transferee from a Series A-1 Stockholder, Series A-2 Stockholder or Series A-3 Stockholder, as the case may be, to whom rights under Section 3 are transferred shall, as a condition to such transfer, deliver to the Corporation a written instrument by which such transferee identifies itself, gives the Corporation notice of the transfer of such rights, identities the securities of the Corporation owned or acquired by it and agrees to be bound by the obligations imposed hereunder to the same extent as if such transferee were a Series A-1 Stockholder, Series A-2 Stockholder or Series A-3 Stockholder, as applicable, hereunder. A transferee to whom rights are transferred pursuant to this Section 7.1 will be thereafter deemed to be a Series A-1 Stockholder, Series A-2 Stockholder or Series A-3 Stockholder, as applicable, for the purpose of the execution of such transferred rights and may not again transfer such rights to any other person or entity, other than as provided in this Section 7.1.

Any transferee from an Other Stockholder to whom rights under Section 3 are transferred shall, as a condition to such transfer, deliver to the Corporation a written instrument by which such transferee identifies itself, gives the Corporation notice of the transfer of such rights, identifies the securities of the Corporation owned or acquired by it and agrees to be bound by the obligations imposed hereunder to the same extent as if such transferee were an Other Stockholder hereunder. A transferee to whom rights are transferred pursuant to this Section 7.2 will be thereafter deemed to be an Other Stockholder for the purpose of the execution of such transferred rights and may not again transfer such rights to any other person or entity, other than as provided in this Section 7.2. Upon the consummation of the Merger: (i) all of the rights and obligations of this Agreement pertaining to the holders of Common Stock and the shares of Common Stock of the Corporation held by them shall be deemed to apply in the same manner to the holders of Common Stock, par value $0.0001 per share of MPMAC, and the shares of such MPMAC Common Stock held by them, respectively, as if such shares of MPMAC stock were shares of Common Stock for all purposes of this Agreement; (ii) all of the rights and obligations of this Agreement pertaining to the Series A-4 Stockholders and the shares of Series A-4 Preferred Stock of the Corporation held by them shall be deemed to apply in the same manner to the holders of Series A-4 Preferred Stock, par value $0.0001 per share of MPMAC, and the shares of such MPMAC Series A-4 Preferred Stock held by them, respectively, as if such shares of MPMAC stock were shares of Series A-4 Preferred Stock for all purposes of this Agreement; (iii) all of the rights and obligations of this Agreement pertaining to the Series A-5 Stockholders and the shares of Series A-5 Preferred Stock of the Corporation held by them shall be deemed to apply in the same manner to the holders of Series A-5 Preferred Stock, par value $0.0001 per share of MPMAC, and the shares of such MPMAC Series A-5 Preferred Stock held by them, respectively, as if such shares of MPMAC stock were shares of Series A-5 Preferred Stock for all purposes of this Agreement; and (iv) all of the rights and obligations of this Agreement pertaining to the Series A-2 Stockholders and the shares of Series A-6 Preferred Stock of the Corporation held by them shall be deemed to apply in the same manner to the holders of Series A-6 Preferred Stock, par value $0.0001 per share of MPMAC, and the shares of such MPMAC Series A-6 Preferred Stock held by them, respectively, as if such shares of MPMAC stock were shares of Series A-6 Preferred Stock for all purposes of this Agreement.

Annex A

PLAN OF DISTRIBUTION

We are registering the shares offered by this prospectus on behalf of the selling stockholders. The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

· ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

· block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

· purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

· an exchange distribution in accordance with the rules of the applicable exchange;

· privately negotiated transactions;

· short sales;

· through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

· broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

· a combination of any such methods of sale; and

· any other method permitted pursuant to applicable law.

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

129

In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering. Upon any exercise of the warrants by payment of cash, however, we will receive the exercise price of the warrants.

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act of 1933, provided that they meet the criteria and conform to the requirements of that rule.

The selling stockholders and any broker-dealers that act in connection with the sale of the shares offered hereby might be deemed to be “underwriters” within the meaning of Section 2(11) of the Securities Act, and any commissions received by such broker-dealers and any profit on the resale of the securities sold by them while acting as principals might be deemed to be underwriting discounts or commissions under the Securities Act.

To the extent required, the shares of our common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

The anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

We have agreed with the selling stockholders to keep the registration statement of which this prospectus constitutes a part effective until the earlier of (1) such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with the registration statement or (2) the date on which the shares may be sold pursuant to Rule 144 of the Securities Act.

APPENDIX A

DEFINITIONS

(1) Affiliate of a specified person (as defined below), means a person who directly or indirectly through one or more intermediaries, controls (as defined below), or is controlled by, or is under common control with, the person specified.

(2) Beneficial, or beneficially, as applied to the ownership of securities, has been defined by the Securities and Exchange Commission to mean the following:

A beneficial owner of a security includes any person (as defined below) who, directly or indirectly, through any contract, arrangement, understanding, relationship, or otherwise has or shares “voting power” and/or “investment power”. Voting power includes the power to vote, or to direct the voting of, such security; investment power includes the power to dispose, or to direct the disposition, of such security.

Note that more than one person may have a beneficial interest in the same securities; one may have voting power and the other may have investment power.

Even if a person, directly or indirectly, creates or uses a trust, proxy, power of attorney, pooling arrangement or any other contract, arrangement or device with the purpose or effect of divesting such person of beneficial ownership of a security or preventing the vesting of such beneficial ownership to avoid the reporting requirements of section 13(d) of the Securities Exchange Act, he will still be deemed to be the beneficial owner of such security.

A person is deemed to be the beneficial owner of a security if that person has the right to acquire beneficial ownership of such security at any time within 60 days, including but not limited to any right to acquire: (i) through the exercise of any option, warrant or right; (ii) through the conversion of a security; (iii) pursuant to the power to revoke a trust, discretionary account, or similar arrangement; or (iv) pursuant to the automatic termination of a trust, discretionary account or similar arrangement.

A member of a national securities exchange is not deemed to be a beneficial owner of securities held directly or indirectly by it on behalf of another person solely because such member is the record holder of such securities and, pursuant to the rules of such exchange, may direct the vote of such securities, without instruction, on other than contested matters or matters that may affect substantially the rights or privileges of the holders of the securities to be voted, but is otherwise precluded by the rules of such exchange from voting without instruction.

A person who in the ordinary course of business is a pledgee of securities pursuant to a bona fide pledge agreement will not be deemed to be the beneficial owner of such pledged securities merely because there has been a default under such an agreement, except during such time as the event of default shall remain uncured for more than 30 days or at any time before a default is cured if the power acquired by the pledgee pursuant to the default enables him to change or influence control of the issuer.

A person may also be regarded as the beneficial owner of securities held in the name of his spouse, his minor children or other relatives of his or her spouse sharing his home, or held in a trust of which he is a beneficiary or trustee, if the relationships are such that he has voting power and/or investment power with respect to such securities.

134

If you have any reason to believe that any interest you have, however remote, might be described as a beneficial interest, describe such interest.

(3) Control means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a person, whether through the ownership of voting securities, by contract, or otherwise.

(4) Person includes two or more persons acting as a partnership, limited partnership, syndicate or other group for the purpose of acquiring, holding, or disposing of securities of an issuer.

Use of Proceeds

1. The Corporation anticipates using the net proceeds from the sale of the Series A-1 Preferred Stock to complete enrollment of the Phase 3 study of the subcutaneous form of the Corporation’s product candidate BA058 (PTHrP analog), complete the Phase 1b study of the transdermal form of BA058, bolster the Corporation’s balance sheet to improve negotiation leverage with potential partners, and to complete a reverse merger with a publicly reporting Form 10 shell enabling the Corporation to eventually become publicly traded and listed on a national securities exchange such as Nasdaq. The amounts actually expended by the Corporation for the above purposes may vary significantly depending on numerous factors, including future revenue growth, if any, the progress of the Corporation’s research and development efforts and technological advances and hence, the Corporation’s management will retain broad discretion in the allocation of the net proceeds from the Series A-1 Preferred Stock.
