The Corporation and its transfer agent may deem and treat the registered Holder of shares of Series A Preferred Stock as the absolute owner thereof for the purpose of any conversion thereof and for all other purposes. Shares of Series A Preferred Stock may be issued solely in book-entry form. The Corporation or its transfer agent shall register the transfer of any shares of Series A Preferred Stock in the Series A Preferred Stock Register, upon surrender of the shares of Series A Preferred Stock evidencing such shares to be transferred, to the Corporation’s transfer agent.

2

transferred, if any, shall be issued to the transferring Holder, in each case, within three Business Days. The provisions of this Certificate of Designations are intended to be for the benefit of all Holders from time to time and shall be enforceable by any such Holder.

Section 3. Dividends. At all times following the Issuance Date, while shares of Series A Preferred Stock are issued and outstanding, holders of Series A Preferred Stock shall be entitled to receive, only when, as and if declared by the Board of Directors, out of any funds and assets legally available therefor, a dividend on each outstanding share of Series A Preferred Stock equal to $0.0001 per share (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Series A Preferred Stock), prior and in preference to any declaration or payment of any dividend (other than dividends on shares of Common Stock payable in shares of Common Stock) on Common Stock during the same calendar year. The right to receive dividends on shares of Series A Preferred Stock pursuant to the preceding sentence of this Section 3 shall not be cumulative, and no right to dividends shall accrue to holders of Series A Preferred Stock by reason of the fact that dividends on such shares are not declared or paid. Payment of any dividends to the holders of Series A Preferred Stock shall be on a pro rata, pari passu basis. Subject to the preferential rights described above, holders of Series A Preferred Stock shall be entitled to receive, and the Corporation shall pay, dividends on shares of Series A Preferred Stock equal (on an as-if-converted-to-Common-Stock basis and without regard to any limitations on conversion set forth herein or otherwise) to and in the same form as dividends actually paid on shares of the Common Stock when, as and if such dividends are paid on shares of the Common Stock (other than a stock dividend on the Common Stock payable solely in the form of additional shares of Common Stock). No other dividends shall be paid on shares of Series A Preferred Stock.

Section 4. Voting Rights.

(a) The Corporation shall not, without the affirmative vote or consent of a majority of the outstanding shares of Series A Preferred Stock, alter or change adversely the powers, preferences or rights of the Series A Preferred Stock or alter or amend this Certificate of Designations of Preferences, Rights and Limitations.

(b) Except as provided in Section 4(a) or as otherwise required by law, holders of shares of the Series A Preferred Stock shall have no voting rights on any Corporation matter.

Section 5. Liquidation. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, including a change of control transaction, or Deemed Liquidation Event (any such event, a “Liquidation”), the assets of the Corporation available for distribution to its stockholders shall be distributed, after payment in full of any dividends declared but unpaid on the Series A Preferred Stock, among the holders of the shares of Series A Preferred Stock and Common Stock pro rata based on the number of shares held by each such holder, treating for this purpose all shares of Series A Preferred Stock as if they had been converted to Common Stock pursuant to the terms of this Certificate of Designations immediately prior to such Liquidation, without regard to any limitations on conversion set forth herein or otherwise and without regard as to whether sufficient shares of Common Stock are available out of the Corporation’s authorized but unissued stock for the purpose of effecting the conversion of the Series A Preferred Stock.

Section 6. Conversion.

(a) Conversions at Option of Holder. Subject to the limitations set forth in Section 6(d), at the option of the Holder thereof, each share of Series A Preferred Stock shall be convertible into a number of shares of Common Stock equal to the quotient of (A) the Stated Price, plus all declared and unpaid dividends, divided by (B) the Conversion Price, rounded down to the nearest whole share of Common Stock (the “Share Conversion Number”). To the extent any conversion in accordance with this Section 6(a) would (i) cause a Holder to beneficially own a number of shares of Common Stock that exceeds the amount that could be issued to such Holder pursuant to Section 6(d) or (ii) in the reasonable judgment of the applicable Holder, result in a violation by such Holder of the Hart Scott Rodino Antitrust Improvements Act of 1976, as amended from time to time (an “HSR Violation”), then, at the Conversion Date, (x) only such portion of such Holder’s shares of Series A Preferred Stock that may be converted without exceeding the limitations in Section 6(d) and without resulting in an HSR Violation shall be converted to Common Stock and (y) the remaining shares of Series A Preferred Stock that would otherwise have been converted into Common Stock shall remain outstanding as Series A Preferred Stock.

(b) Mechanics of Conversion.

(i) Notice of Conversion. Holders shall effect conversions pursuant to Section 6(a) by providing the Corporation and its transfer agent with the form of conversion notice attached hereto as Annex A (a “Notice of Conversion”), duly completed and executed. The Notice of Conversion must specify the number of shares of Series A Preferred Stock to be converted, the number of shares of Series A Preferred Stock owned immediately prior to the conversion at issue, and the number of shares of Common Stock to be issued in respect of the conversion at issue. Provided the Corporation’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program, and that the Conversion Shares may be issued free of restrictive legends pursuant to Section 4.1 of the Securities Purchase Agreement, and subject to compliance with applicable securities laws, the Notice of Conversion may specify, at the Holder’s election, whether the applicable Conversion Shares shall be credited to the DTC participant account nominated by the Holder through DTC’s Deposit Withdrawal Agent Commission system (such system, “DWAC System” and any such delivery, a “DWAC Delivery”). Absent such Holder’s election, any such Conversion Shares will be credited to the Holder’s account in book-entry form at the Corporation’s transfer agent and shall bear the restrictive legend set forth in Section 4.1 of the Securities Purchase Agreement. The date on which such a conversion shall be deemed effective (a “Conversion Date”), shall be defined as the Trading Day that the Notice of Conversion, completed and executed, is sent by facsimile or other electronic transmission to, and received during regular business hours by, the Corporation and its transfer agent, or at such later time as is specified in the Notice of Conversion. The calculations set forth in the Notice of Conversion shall control in the absence of manifest or mathematical error.

(ii) Delivery of Electronic Issuance Upon Conversion. Not later than the number of Trading Days comprising the Standard Settlement Period after the applicable Conversion Date (the “Share Delivery Date”), the Corporation’s transfer agent shall (a) in the case of a DWAC Delivery (if so requested by the Holder and subject to compliance with applicable securities laws and Section 4.1 of the Securities Purchase Agreement), electronically transfer such Conversion Shares by crediting the DTC participant account nominated by the Holder through the DWAC System or (b) if the shares of Series A Preferred stock being converted have been issued in global form eligible for book-entry settlement with DTC, the Conversion Shares shall be delivered to the Holder through book-entry transfer through the facilities of DTC (if so requested by the Holder and subject to compliance with applicable securities laws and Section 4.1 of the Securities Purchase Agreement). If, in the case of a DWAC Delivery, such shares are not electronically delivered to or as directed by the applicable Holder by the Share Delivery Date, the applicable Holder shall be entitled to elect to rescind any Notice of Conversion by written notice to the Corporation and its transfer agent at any time on or before its electronic receipt of such shares, as applicable, in which event the Corporation’s transfer agent shall promptly direct the return of any shares of Common Stock delivered to the Holder through the DWAC System, representing the shares of Series A Preferred Stock unsuccessfully tendered for conversion to the Corporation. It is understood and agreed that the Conversion Shares are restricted securities and shall bear the restrictive legend set forth in Section 4.1 of the Securities Purchase Agreement, provided, however, that such restrictive legends may be removed subject and pursuant to the provisions of Section 4.1(c) of the Securities Purchase Agreement.

(iii) Obligation Absolute. Subject to the Holder’s right to rescind a Notice of Conversion pursuant to Section 6(b)(ii) above, the Corporation’s obligation to issue and deliver the Conversion Shares upon conversion of Series A Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by a Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such Holder or any other Person of any obligation to the Corporation or any violation or alleged violation of law by such Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Corporation to such Holder in connection with the issuance of such Conversion Shares. Nothing herein shall limit a Holder’s right to pursue actual damages for the Corporation’s failure to deliver Conversion Shares within the period specified herein and such Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief; provided that such Holder shall not receive duplicate damages for the Corporation’s failure to deliver Conversion Shares within the period specified herein. The exercise of any such rights shall not prohibit a Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

(iv) Compensation for Buy-In on Failure to Timely Deliver Shares Upon Conversion. If the Corporation fails to effect a DWAC Delivery, as applicable, by the Share Delivery Date pursuant to Section 6(b)(i) (other than a failure caused by incorrect or incomplete information provided by the Holder to the Corporation), and if after such Share Delivery Date such Holder is required to purchase (in an open market

4

transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of such Conversion Shares which such Holder was entitled to receive from the Corporation without any restrictive legend relating to such Share Delivery Date (a “Buy-In”), then the Corporation shall, within four (4) Trading Days after such Holder’s request and in such Holder’s sole discretion, (A) pay in cash to such Holder (in addition to any other remedies available to or elected by such Holder) the amount by which (x) such Holder’s total purchase price (including any brokerage commissions) for the shares of Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such Holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of such Holder, either reissue (if surrendered) the shares of Series A Preferred Stock equal to the number of shares of Series A Preferred Stock submitted for conversion or deliver to such Holder the number of shares of Common Stock that would have been issued if the Corporation had timely complied with its delivery requirements under Section 6(b)(ii). For example, if a Holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Series A Preferred Stock, with respect to which the actual sale price (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Corporation shall be required to pay such Holder $1,000. The Holder shall provide the Corporation written notice, within three (3) Trading Days after the occurrence of a Buy-In, indicating the amounts payable to such Holder in respect of such Buy-In together with applicable confirmations and other evidence reasonably requested by the Corporation. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Corporation’s failure to timely deliver shares of Common Stock upon conversion of the shares of Series A Preferred Stock as required pursuant to the terms hereof; provided, however, that the Holder shall not be entitled to both (i) require the reissuance of the shares of Series A Preferred Stock submitted for conversion for which such conversion was not timely honored and (ii) receive the number of shares of Common Stock that would have been issued if the Corporation had timely complied with its delivery requirements under Section 6(b)(i).

(v) Reservation of Shares Issuable Upon Conversion. The Corporation covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Series A Preferred Stock, free from preemptive rights or any other actual or contingent purchase rights of Persons other than the Holders of the Series A Preferred Stock, not less than such aggregate number of shares of the Common Stock as shall be issuable (taking into account the adjustments of Section 7) upon the conversion of all outstanding shares of Series A Preferred Stock. Such reservation shall comply without regard to the provisions of Section 6(d). The Corporation covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid, non-assessable and free and clear of all liens and other encumbrances.

(vi) Fractional Shares. No fractional shares or scrip representing fractional shares of Common Stock shall be issued upon the conversion of the Series A Preferred Stock. All fractional shares shall be rounded down to the nearest whole shares of Common Stock.

(vii) Transfer Taxes. The issuance of book entry notations for Conversion Shares shall be made without charge to any Holder for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such book entry notation, provided that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such book entry notation upon conversion in a name other than that of the registered Holder(s) of such shares of Series A Preferred Stock and the Corporation shall not be required to issue or deliver such book entry notation unless or until the Person or Persons requesting the issuance thereof shall have paid to the Corporation the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid.

(c) Status as Stockholder. Upon each Conversion Date in which shares of the Series A Preferred Stock converts into Common Stock: (i) the shares of Series A Preferred Stock being converted shall be deemed converted into shares of Common Stock; and (ii) the Holder’s rights as a holder of such converted shares of Series A Preferred Stock shall cease and terminate, excepting only the right to receive book entry notations for such shares of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because of a failure by the Corporation to comply with the terms of this Certificate of Designations. In all cases, the holder shall retain all of its rights and remedies for the Corporation’s failure to convert Series A Preferred Stock.

5

(d) Limitations on Conversion. Except as set forth in this Section 6(d), a Holder shall not have the right to convert any portion of the Series A Preferred Stock or take delivery of shares of Common Stock upon any conversion of shares of Series A Preferred Stock, nor shall the Corporation have any obligation to effect any purported conversion, in each case, to the extent that after giving effect to such conversion, action or delivery, as applicable, such Holder (together with such Holder’s Affiliates, any other Persons acting as a group together, and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Holder’s and the other Attribution Parties for purposes of Section 13(d) of the Exchange Act (such Persons, “Attribution Parties”)) would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such conversion. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock held and/or beneficially owned by such Holder and its Attribution Parties shall include the number of shares of Common Stock held by the Holder and all other Attribution Parties plus the number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (i) exercise of the remaining, unconverted portion of the Series A Preferred Stock beneficially owned by such Holder and its Attribution Parties and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Corporation beneficially owned by such Holder and its Attribution Parties (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. For purposes of this Section 6(d), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Corporation’s most recent Form 10-K, Proxy Statement, Form 10-Q, Current Report on Form 8-K or other public filing with the Commission, as the case may be, (2) a more recent public announcement by the Corporation or (3) any other notice by the Corporation or the Corporation’s transfer agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of a Holder, where such request indicates that it is being made pursuant to this Section 6(d), the Corporation shall within one (1) Trading Day confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. The Holder shall disclose to the Corporation the number of shares of Common Stock that it, together with the Attribution Parties holds and/or beneficially owns and has the right to acquire through the conversion of the shares of Series A Preferred Stock and any limitations on conversion analogous to the limitation contained herein contemporaneously or immediately prior to submitting a Notice of Conversion. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Corporation, including the Series A Preferred Stock, by a Holder and its Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. In the event that the issuance of shares of Common Stock to the Holder upon the conversion of any of such Holder’s shares of Series A Preferred Stock results in the Holder and the other Attribution Parties being deemed to beneficially own, in the aggregate, more than the Maximum Percentage of the number of outstanding shares of Common Stock, the number of shares so issued by which such Holder’s and the other Attribution Parties’ aggregate beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void and shall be cancelled ab initio, and such Holder shall not have the power to vote or to transfer the Excess Shares. As soon as reasonably practicable after the issuance of the Excess Shares has been deemed null and void and/or any other shares of Series A Preferred Stock have been purported to be converted or mandatorily converted in excess of the limitations set forth in this Section 6(d), the Corporation shall return to the Holder the number of shares of Series A Preferred Stock corresponding to such excess. Upon delivery of a written notice to the Corporation, a Holder may from time to time increase or decrease the Maximum Percentage to any other percentage (not in excess of 19.99% of the issued and outstanding Common Stock immediately after giving effect to the issuance of the Common Stock issuable upon conversion of the Series A Preferred Stock if exceeding that limit would result in a change of control under Nasdaq Listing Rule 5635(b) or any successor rule) as specified in such notice; provided that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first (61^st) day after such notice is delivered to the Corporation and (ii) any such increase or decrease will apply only to such Holder and other Attribution Parties and not to any other holder of Series A Preferred Stock, provided, for the avoidance of doubt, that no such decrease shall affect the validity of any prior conversion of the Series A Preferred Stock by a Holder or any Attribution Party. For purposes of clarity, the shares of Common Stock issuable pursuant to the terms hereof in excess of the Maximum Percentage shall not be deemed to be beneficially owned by a Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the Exchange Act. No prior inability to convert Series A Preferred Stock pursuant to this Section 6(d) shall have any effect on the applicability of the provisions of this Section 6(d) with respect to any subsequent determination of whether Series A Preferred Stock may be converted. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 6(d) to the extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent with the intended beneficial ownership limitation contained in this Section 6(d) or to make changes or supplements necessary or desirable to properly give effect to such limitation.

Section 7. Certain Adjustments.

(a) Stock Dividends and Stock Splits. If the Corporation, at any time while any shares of Series A Preferred Stock are outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions payable in shares of Common Stock with respect to the then outstanding shares of Common Stock; (ii) subdivides outstanding shares of Common Stock into a larger number of shares; or (iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding any treasury shares of the Corporation) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event (excluding any treasury shares of the Corporation). Any adjustment made pursuant to this Section 7(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination.

(b) Reclassification, Exchange or Substitution. If the Common Stock issuable upon the conversion of the Series A Preferred Stock shall be changed into the same or a different number of shares of any class or classes of stock, whether by capital reorganization, reclassification, or otherwise (other than a subdivision or combination of shares or stock dividend provided for above, or a reorganization, merger, consolidation, or sale of assets provided for below), then and in each such event the holder of each such share of Series A Preferred Stock shall have the right thereafter to convert such share into the kind and amount of shares of stock and other securities and property receivable, upon such reorganization, reclassification, or other change, by holders of the number of shares of Common Stock into which such shares of Series A Preferred Stock might have been converted immediately prior to such reorganization, reclassification, or change, all subject to further adjustment as provided herein.

(c) Merger or Reorganization, etc. If there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving the Corporation in which the Common Stock (but not the Series A Preferred Stock) is converted into or exchanged for securities, cash or other property (other than a transaction covered by paragraphs (a) or (b) of this Section 7), then, following any such reorganization, recapitalization, reclassification, consolidation or merger, each share of Series A Preferred Stock shall be convertible into the kind and amount of securities, cash or other property which a holder of the number of shares of Common Stock of the Corporation issuable upon conversion of one share of Series A Preferred Stock immediately prior to such reorganization, recapitalization, reclassification, consolidation or merger would have been entitled to receive pursuant to such transaction (without regard to any limitation in Section 6(d) on the conversion of the Convertible Preferred Stock); and, in such case, appropriate adjustment (as determined in good faith by the Board of Directors) shall be made in the application of the provisions in this Section 7 with respect to the rights and interests thereafter of the holders of the Series A Preferred Stock to the end that the provisions set forth in this Section 7 (including provisions with respect to changes in and other adjustments of the Conversion Price, as applicable) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities or other property thereafter deliverable upon the conversion of the Series A Preferred Stock.

(d) Calculations. All calculations under this Section 7 shall be made to the nearest cent or the nearest 1/100^th of a share, as the case may be. For purposes of this Section 7, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares of the Corporation) issued and outstanding.

(e) Notice to the Holders.

(i) Adjustment to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 7, the Corporation shall promptly deliver to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

(ii) Other Notices. If (A) the Corporation shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Corporation shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Corporation shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Corporation shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Corporation is a party, any sale or transfer of all or substantially all of the assets of the Corporation, or any compulsory share exchange whereby

7

the Common Stock is converted into other securities, cash or property, or (E) the Corporation shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Corporation, then, in each case, the Corporation shall cause to be filed at each office or agency maintained for the purpose of conversion of the shares of Series A Preferred Stock, and shall cause to be delivered to each Holder at its last address as it shall appear upon the stock books of the Corporation, at least 10 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distribution, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange, provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice; and provided further, that in each case, the Corporation will only be required to provide such information to the Holder if such information shall have be made known to the public prior to or in conjunction with such notice being provided to the Holder.

Section 8. Miscellaneous.

(a) Waiver. Any waiver by the Corporation or a Holder of a breach of any provision of this Certificate of Designations shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Certificate of Designations or a waiver by any other Holders. The failure of the Corporation or a Holder to insist upon strict adherence to any term of this Certificate of Designations on one or more occasions shall not be considered a waiver or deprive that party (or any other Holder) of the right thereafter to insist upon strict adherence to that term or any other term of this Certificate of Designations. Any waiver by the Corporation or a Holder must be in writing. Notwithstanding any provision in this Certificate of Designations to the contrary, any provision contained herein and any right of the Holders of Series A Preferred Stock granted hereunder may be waived as to all shares of Series A Preferred Stock (and the Holders thereof) upon the written consent of a majority of shares of Series A Preferred Stock, unless a higher percentage is required by the DGCL, in which case the written consent of the Holders of not less than such higher percentage shall be required.

(b) Severability.

3.2 Representations and Warranties of the Purchaser. The Purchaser hereby represents and warrants as of the date hereof and as of the Closing Date to the Company as follows:

(a) Organization; Authority. The Purchaser is an entity validly existing and in good standing under the laws of the jurisdiction of its organization with the requisite corporate or partnership power and authority to enter into and to consummate the transactions contemplated by the applicable Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of this Agreement by the Purchaser and performance by the Purchaser of the transactions contemplated by this Agreement have been duly authorized by all necessary corporate action on the part of the Purchaser. Each Transaction document to which the Purchaser is a party has been duly executed by the Purchaser, and when delivered by the Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of the Purchaser, enforceable against it in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by other equitable principles of general application.

(b) No Conflicts. The execution, delivery and performance by the Purchaser of this Agreement and the consummation by the Purchaser of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of the Purchaser, (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Purchaser is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to the Purchaser, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of the Purchaser to perform its obligations hereunder.

(c) Investment Intent. The Purchaser understands that the Securities are “restricted securities” and have not been registered under the Securities Act or any applicable state securities law and is acquiring the Shares and will acquire the Conversion Shares (upon conversion of the Shares) as principal for its own account and not with a view to, or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities laws, provided, however, that by making the representations herein, subject to the provisions of this Agreement, the Purchaser does not agree to hold any of the Securities for any minimum period of time and reserves the right at all times to sell or otherwise dispose of all or any part of such Securities pursuant to an effective registration statement under the Securities Act or under an exemption from such registration and in compliance with applicable federal and state securities laws. The Purchaser does not presently have any agreement, plan or understanding, directly or indirectly, with any Person to distribute or effect any distribution of any of the Securities (or any securities which are derivatives thereof) to or through any person or entity; the Purchaser is not a registered broker-dealer under Section 15 of the Exchange Act or an entity engaged in a business that would require it to be so registered as a broker-dealer.

(d) Purchaser Status. At the time the Purchaser was offered the Shares, it was, and at the date hereof it is, an “accredited investor” as defined in Rule 501(a) under the Securities Act.

The Purchaser acknowledges that it has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and the Subsidiaries and their respective financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. Neither such inquiries nor any other investigation conducted by or on behalf of the Purchaser or its representatives or counsel shall modify, amend or affect the Purchaser’s right to rely on the truth, accuracy and completeness of the SEC Reports and the Company’s representations and warranties contained in the Transaction Documents. The Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed decision with respect to its acquisition of the Securities.

20

(g) Certain Trading Activities. Other than with respect to the transactions contemplated herein, since the time that the Purchaser was first contacted by the Company or any other Person regarding the transactions contemplated hereby, neither the Purchaser nor any Affiliate of the Purchaser which (x) had knowledge of the transactions contemplated hereby, (y) has or shares discretion relating to the Purchaser’s investments or trading or information concerning the Purchaser’s investments, including in respect of the Securities, and (z) is subject to the Purchaser’s review or input concerning such Affiliate’s investments or trading (collectively, “Trading Affiliates”) has directly or indirectly, nor has any Person acting on behalf of or pursuant to any understanding with the Purchaser or Trading Affiliate, effected or agreed to effect any purchases or sales of the securities of the Company (including, without limitation, any Short Sales involving the Company’s securities).

No Person will have, as a result of the transactions contemplated by this Agreement, any valid right, interest or claim against or upon the Company or the Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of the Purchaser.

(i) Independent Investment Decision. The Purchaser has independently evaluated the merits of its decision to purchase Securities pursuant to the Transaction Documents. The Purchaser understands that nothing in this Agreement or any other materials presented by or on behalf of the Company to the Purchaser in connection with the purchase of the Securities constitutes legal, tax or investment advice. The Purchaser has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Securities. The Purchaser confirms that none of such Persons has made any representations or warranties to the Purchaser in connection with the transactions contemplated by the Transaction Documents.

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

4.1 Transfer Restrictions.

(a) Compliance with Laws. Notwithstanding any other provision of this Article IV, the Purchaser covenants that the Securities may be disposed of only pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act, or pursuant to an available exemption from, or in a transaction not subject to, the registration requirements of the Securities Act, and in compliance with any applicable state and federal securities laws. In connection with any transfer of the Securities other than (i) pursuant to an effective registration statement, (ii) to the Company or (iii) pursuant to Rule 144 (provided that the Purchaser provides the Company with reasonable assurances (in the form of seller and, if applicable, broker representation letters) that the securities may be sold pursuant to such rule), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act. As a condition of a transfer other than pursuant to (i) through (iii) above, any such transferee shall agree in writing to be bound by the terms of this Agreement, including for the avoidance of doubt Section 4.15 and Section 4.16, and shall have the rights of the Purchaser under this Agreement with respect to such transferred Securities.

(b) Legends. Certificates, including, if applicable, book-entry statements with the Transfer Agent, evidencing the Securities shall bear any legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form, until such time as they are not required under Section 4.1(c):

NEITHER THESE SECURITIES NOR THE SECURITIES ISSUABLE UPON CONVERSION OF THESE SECURITIES HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES AND THE SECURITIES ISSUABLE UPON CONVERSION OF THESE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OR (B) AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY AND ITS TRANSFER AGENT OR (II) UNLESS SOLD PURSUANT TO RULE 144 UNDER THE SECURITIES ACT.

(c) Removal of Legends. The legend set forth in Section 4.1(b) above shall be removed and the Company shall, or shall cause its Transfer Agent to, as applicable, issue book-entry statements without such legend or any other legend to the holder of the Conversion Shares upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at the Depository Trust Company (“DTC”), if (i) such Conversion Shares have been sold or transferred pursuant to (x) the plan of distribution set forth in an effective registration statement registering the Conversion Shares for resale (during such time that such registration statement is effective and not withdrawn or suspended) or (y) Rule 144, in each case upon delivery by the Purchaser to the Company, the Transfer Agent, as applicable, and Company Counsel of a customary seller’s representation letter and broker’s representation letter confirming the transfer of such Conversion Shares in the manner described in this clause (i), together with any other documentation reasonably required by the Transfer Agent and/or the Depository Trust Company (the “Resale Deliverables”), or (ii) in the absence of any sale of the Conversion Shares, following the date that is the one-year anniversary of the Closing Date and if requested by the Purchaser in writing, if such Conversion Shares are eligible for sale under Rule 144, without compliance with any of the requirements of such rule, including the current public information requirement and without volume or manner-of-sale

22

restrictions, upon delivery by the Purchaser to the Company, the Transfer Agent, as applicable, and Company Counsel of a customary representation letter from the Purchaser confirming that the requirements set forth in this clause (ii) have been satisfied, together with any other documentation reasonably required by the Transfer Agent and/or the Depository Trust Company (the “Non-Resale Deliverables”). Any fees (with respect to the Transfer Agent, Company Counsel or otherwise) associated with the issuance of such opinion or the removal of such legend pursuant to the immediately preceding sentence shall be borne by the Company. The Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4.1(c). Electronic certificates for Conversion Shares subject to legend removal hereunder may be transmitted by the Transfer Agent to the Purchaser by crediting the account of the Purchaser’s prime broker with DTC as directed by the Purchaser.

(d) Irrevocable Transfer Agent Instructions. Subject to the terms and conditions of this Agreement and the Securities Act, the Company shall issue irrevocable instructions to its Transfer Agent, and any subsequent transfer agent, in the form of Exhibit D attached hereto (the “Irrevocable Transfer Agent Instructions”). The Company represents and warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 4.1(d) (or instructions that are consistent therewith) will be given by the Company to its transfer agent in connection with this Agreement, and that the Securities shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the other Transaction Documents and applicable law. The Company acknowledges that a breach by it of its obligations under this Section 4.1(d) will cause irreparable harm to the Purchaser. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 4.1(d) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 4.1(d), that the Purchaser shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

(e) Acknowledgement. The Purchaser hereunder acknowledges its primary responsibilities under the Securities Act and accordingly will not sell or otherwise transfer the Securities or any interest therein without complying with the requirements of the Securities Act. While the Registration Statement remains effective, the Purchaser hereunder may sell the Conversion Shares in accordance with the plan of distribution contained in the Registration Statement and if it does so it will comply therewith and with the related prospectus delivery requirements unless an exemption therefrom is available. The Purchaser agrees that if it is notified by the Company in writing at any time that the Registration Statement registering the resale of the Conversion Shares is not effective or that the prospectus included in such Registration Statement no longer complies with the requirements of Section 10 of the Securities Act, the Purchaser will refrain from selling such Conversion Shares until such time as the Purchaser is notified by the Company that such Registration Statement is effective or such prospectus is compliant with Section 10 of the Securities Act, unless the Purchaser is able to, and does, sell such Conversion Shares pursuant to an available exemption from the registration requirements of Section 5 of the Securities Act.

(f) Buy-In. If the Company shall fail for any reason or for no reason to issue via DTC to the Purchaser Conversion Shares that are free from all restrictive and other legends within the number of Trading Days comprising the Standard Settlement Period following receipt of all documents and information necessary for the removal of the legend set forth above (other than a failure caused by incorrect or incomplete information provided by the Purchaser to the Company), then, in addition to all other remedies available to the Purchaser, if on or after the Trading Day immediately following the number of Trading Days comprising the Standard Settlement Period, the Purchaser is required to purchase (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Purchaser of such Conversion Shares that the Purchaser was entitled to receive from the Company without any restrictive legend (a “Buy-In”), then the Company shall, within four (4) Trading Days after the Purchaser’s request and in the Purchaser’s sole discretion, (A) pay in cash to the Purchaser the amount by which (x) the Purchaser’s total purchase price (including any brokerage commissions) for the shares of Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common

23

Stock that the Purchaser was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of the Purchaser, either reissue (if surrendered) the Shares equal to the number of Shares submitted for conversion or deliver to the Purchaser the number of shares of Common Stock that would have been issued if the Company had timely complied with its delivery requirements under this Section 4.1. The Purchaser shall provide the Company written notice, within three (3) Trading Days after the occurrence of a Buy-In, indicating the amounts payable to the Purchaser in respect of such Buy-In together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit the Purchaser’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares of Common Stock upon conversion of the shares of Series A Preferred Stock as required pursuant to the terms hereof; provided, however, that the Purchaser shall not be entitled to both (i) require the reissuance of the shares of Series A Preferred Stock submitted for conversion for which such conversion was not timely honored and (ii) receive the number of shares of Common Stock that would have been issued if the Company had timely complied with its delivery requirements under this Section 4.1.

4.2 Reservation of Stock. The Company shall take all action necessary to at all times have authorized and reserved for the purpose of issuance from and after the Closing Date, for so long as any of the Shares are outstanding, and to reserve and keep available out of its authorized and unissued capital stock, solely for the purpose of effecting the conversion of the Shares, the maximum number of shares of Common Stock issuable upon the exercise or conversion thereof (without taking into account any limitations set forth in the Certificate of Designations).

4.3 Furnishing of Information. In order to enable the Purchaser to sell the Securities under Rule 144, for a period of twelve (12) months from the Closing, the Company shall use its commercially reasonable efforts to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the Closing Date pursuant to the Exchange Act. During such twelve (12) month period, if the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to the Purchaser and make publicly available in accordance with Rule 144(c) such information as is required for the Purchaser to sell the Securities under Rule 144.

4.4 Integration. The Company shall not, and shall use its commercially reasonable efforts to ensure that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchaser, or that will be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market such that it would require stockholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction.

4.5 Securities Laws Disclosure; Publicity. On or before the second (2^nd) Trading Day immediately following the date hereof, the Company shall issue a press release reasonably acceptable to the Purchaser. On or before the second (2nd) Trading Day immediately following the execution of this Agreement, the Company will file the Transaction 8-K with the Commission. Notwithstanding the foregoing, the Company shall not publicly disclose the name of the Purchaser or an Affiliate of the Purchaser, or include the name of the Purchaser or an Affiliate of the Purchaser in any press release or filing with the Commission (other than the Registration Statement) or any regulatory agency or Trading Market, without the prior written consent of the Purchaser, such consent not to be unreasonably withheld, except (i) as required by federal securities law in connection with (A) any registration statement contemplated by Section 4.15 hereto and (B) the filing of final Transaction Documents (including signature pages thereto) with the Commission and (ii) to the extent such disclosure is required by law, request of the Staff or Trading Market regulations, in which case the Company shall provide the Purchaser with prior written notice of such disclosure permitted under this subclause (ii). As of immediately after the issuance of the Transaction 8-K, the Purchaser shall not be in possession of any material, non-public information

24

received from the Company, any Subsidiary or any of their respective officers, directors, employees or agents, that is not disclosed in the Transaction 8-K. The Purchaser covenants that until such time as the transactions contemplated by this Agreement are required to be publicly disclosed by the Company as described in this Section 4.5, the Purchaser will maintain the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction); provided, however, that any disclosure may be made by the Purchaser solely on a need-to-know basis to the Purchaser’s representatives or agents (including, but not limited to, the Purchaser’s legal, tax and investment advisors) that are bound by obligations of confidentiality and restrictions against disclosure of any confidential information.

4.6 Non-Public Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, including this Agreement and the ROFN, or as expressly required by any applicable securities law, the Company covenants and agrees that neither it, nor any other Person acting on its behalf, will provide the Purchaser or its agents or counsel with any information regarding the Company that the Company believes constitutes material non-public information without the express written consent of the Purchaser, except as contemplated under the ROFN or pursuant to Section 4.7 or Section 4.14. The Company understands and confirms that the Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.

4.7 Observer Rights. Notwithstanding the restrictions of Section 4.6, for so long as the Purchaser owns at least 50% of the Shares it is purchasing under this Agreement (or an equivalent amount of Common Stock issued upon conversion thereof) (as adjusted for stock splits, stock combinations, stock dividends and the like), the Company shall invite a representative of the Purchaser to attend all meetings of the Company’s clinical advisory committee and scientific advisory board (or the most comparable relevant standing technical committees) (the “Committees”), and shall give such representative copies of all notices and other materials that it provides to the members of such committees at the same time and in the same manner as provided to such members; provided, however, that (a) such representative shall only be permitted to attend portions of such Committee meetings and receive portions of such materials that relate to VTX3232 or the VTX3232 Program, (b) such representative shall agree to hold in confidence all information so provided pursuant to an executed confidentiality agreement between such representative and the Company in a form acceptable to the Company; and (c) the Company reserves the right to withhold any information and to exclude such representative from any meeting or portion thereof if access to such information or attendance at such meeting would be reasonably likely to adversely affect the attorney-client privilege between the Company and its counsel or result in the disclosure of trade secrets.

4.9 Use of Proceeds. The Company shall use the net proceeds from the sale of the Shares hereunder for working capital and general corporate purposes.

Promptly after receipt by any Person (the “Indemnified Person”) of notice of any demand, claim or circumstances which would or might give rise to a claim or the commencement of any action, proceeding or investigation in respect of which indemnity may be sought

pursuant to this Section 4.10, such Indemnified Person shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the payment of all fees and expenses; provided, however, that the failure of any Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder except to the extent that the Company is actually and materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless: (i) the Company and the Indemnified Person shall have mutually agreed to the retention of such counsel; (ii) the Company shall have failed promptly to assume the defense of such proceeding and to employ counsel reasonably satisfactory to such Indemnified Person in such proceeding; or (iii) in the reasonable judgment of counsel to such Indemnified Person, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Company shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned. Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, delayed or conditioned, the Company shall not effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding.

4.11 Principal Trading Market Listing. In the time and manner required by the Principal Trading Market, the Company shall prepare and file with such Principal Trading Market a Notification of Listing of Additional Shares covering all of the Conversion Shares.

4.12 Form D; Blue Sky. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D, if applicable, and to provide a copy thereof, promptly upon the written request of the Purchaser. The Company, on or before the Closing Date, if applicable, shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for or to qualify the Securities for sale to the Purchaser under applicable securities or “Blue Sky” laws of the states of the United States (or to obtain an exemption from such qualification) and shall provide evidence of such actions promptly upon the written request of the Purchaser.

4.13 Delivery of Shares After Closing. Within three (3) Business Days after the Closing Date, the Company shall deliver, or cause to be delivered, a physical copy of the Stock Certificate to the Purchaser at the mailing address specified on the Stock Certificate Questionnaire included as Exhibit C.

4.14 Subsequent Equity Sales. Except for an Exempt Issuance, from the date hereof until the later of (a) the Effective Date, and (b) the date that is sixty (60) days after the Closing Date, neither the Company nor any Subsidiary shall, without the consent of the Purchaser, issue shares of Common Stock or Common Stock Equivalents.

4.15 Registration Rights.

(a) Registration Procedures and Expenses. The Company shall:

(i) as soon as practicable following Closing, but, in any event, not later than forty-five (45) days thereafter, use commercially reasonable efforts to prepare and file a registration statement (the “Registration Statement”) with the Commission to register the offer and sale to the public of all of the Registrable Shares on Form S-3 under the Securities Act (providing for shelf registration of such Registrable Shares under Commission Rule 415) (or, if Form S-3 is not then available to the Company, on such form of registration statement as is then available to effect a registration for resale for the Registrable Shares provided that the Company undertakes to register the Registrable Shares on Form S-3 as soon as such form becomes available to the Company, and the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Shares has been declared effective by the SEC) covering the resale of all of the Registrable Shares (the date on which such Registration Statement is filed by the Company with the

26

Commission, the “Filing Date”). It shall be a condition precedent to the obligations of the Company to file the Registration Statement that the Purchaser furnish to the Company (x) a customary completed selling stockholder questionnaire and (y) such further information regarding the Purchaser, the Registrable Shares held by the Purchaser and the intended method of disposition of the Registrable Shares held by the Purchaser as shall be reasonably required to effect the effectiveness of the registration of the Registrable Shares. In the event that Form S-3 is not available for the registration of the Registrable Shares, the Company shall register the offer and sale to the public of the Registrable Shares on such other Registration Statement form as is available to the Company and undertake to register the Registrable Shares on Form S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Shares has been declared effective by the Commission;

(ii) use its commercially reasonable efforts to cause such Registration Statement required by Section 4.15(a)(i) to be declared effective within fifteen (15) days following the Filing Date (or, in the event the Staff reviews and has written comments to the Registration Statement, within forty-five (45) days following the Filing Date) (the earlier of the foregoing or the applicable date set forth in Section 4.15(a)(vi), the “Effectiveness Deadline”), such efforts to include, without limiting the generality of the foregoing, preparing and filing with the Commission any financial statements or other information that is required to be filed prior to the effectiveness of such Registration Statement;

(iii) prepare and file with the Commission such amendments and supplements to any Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement continuously effective and free from any material misstatement or omission to state a material fact therein until the earlier of: (A) the date as of which all Registrable Shares have been sold pursuant to the Registration Statement and (B) that date as of which no Registration Shares remain outstanding, subject to the Company’s right to suspend pursuant to Section 4.15(g);

(iv) furnish to the Purchaser such number of copies of prospectuses in conformity with the requirements of the Securities Act and such other documents as the Purchaser may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Registrable Shares by the Purchaser;

(v) file such documents as may be required of the Company for normal securities law clearance for the offer and sale of the Registrable Shares in such states of the United States as may be reasonably requested by the Purchaser and use its commercially reasonable efforts to maintain such blue sky qualifications during the period the Company is required to maintain effectiveness of the Registration Statement; provided, however, that the Company shall not be required in connection with this Section 4.15(a)(v) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction in which it is not now so qualified or has not so consented or subject the Company to any material tax in any such jurisdiction where it is not then so subject;

(vi) use its commercially reasonable efforts to, upon notification by the Commission that the Registration Statement will not be reviewed or is not subject to further review by the Commission, within three (3) Trading Days following the date of such notification, request acceleration of such Registration Statement (with the requested effectiveness date to be not more than two (2) Trading Days later);

(vii) upon notification by the Commission that that the Registration Statement has been declared effective (the date of such notification, the “Effective Date”) by the Commission, file the final prospectus under Rule 424 within the applicable time period prescribed by Rule 424;

(viii) advise the Purchaser promptly, and in any event within twenty-four (24) hours of (A) the effectiveness of the Registration Statement or any post-effective amendments thereto, (B) any request by the Commission for amendments to the Registration Statement or amendments to the prospectus or for additional information relating thereto, (C) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement under the Securities Act or of the

27

suspension by any state securities commission of the qualification of the Registrable Shares for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes and (D) the existence of any fact and the happening of any event that makes any statement of a material fact made in the Registration Statement, the prospectus and amendment or supplement thereto, or any document incorporated by reference therein, untrue, or that requires the making of any additions to or changes in the Registration Statement or the prospectus in order to make the statements therein not misleading;

(ix) cause all Registrable Shares to be listed on each securities exchange on which equity securities by the Company are then listed, if any; and

(x) bear all expenses in connection with the procedures in paragraphs (i) through (ix) of this Section 4.15(a) and the registration of the Registrable Shares on such Registration Statement and the satisfaction of the blue sky laws of such states.

(b) Liquidated Damages. If (i) the Registration Statement covering the Registrable Shares is not filed with the Commission on or prior to the Filing Date or (ii) the Registration Statement covering the Registrable Shares is not declared effective by the SEC by the Effectiveness Deadline (each such event, a “Registration Failure”), then, in addition to any other rights the Purchaser may have hereunder or under applicable law, the Company will make a liquidated damages payment to the Purchaser and not as a penalty (the “Liquidated Damages”), in an amount equal to one percent (1.0%) of the aggregate amount invested by the Purchaser for the Registrable Shares then held by the Purchaser for the initial day of a Registration Failure and, thereafter in an amount equal to one percent (1.0%) for each thirty (30)-day period until such Registration Failure is cured. The Liquidated Damages shall be paid monthly within ten (10) business days of the date of such Registration Failure and the end of each subsequent thirty (30)-day period (or portion thereof with respect to a final period, if any) thereafter until the Registration Failure is cured. Such payments shall be made in cash to the Purchaser. Interest shall accrue at the rate of one percent (1.0%) per month on any such liquidated damages payments that shall not be paid by the applicable payment date until such amount is paid in full. The parties agree that notwithstanding anything to the contrary herein, no Liquidated Damages shall be payable if (i) the Registrable Shares may be sold without volume or manner of sale restrictions under Rule 144, as determined by counsel to the Company pursuant to a written opinion letter to such effect, addressed and reasonably acceptable to the Purchaser and the Company’s transfer agent, (ii) the Registration Failure is caused by any action or inaction of the Purchaser, or (iii) the Purchaser is unable to lawfully sell any of its Registrable Shares because of possession of material non-public information.

(c) Rule 415 Cutback. If at any time the Staff takes the position that the offering of some or all of the Registrable Shares in a Registration Statement is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the Securities Act or requires the Purchaser to be named as an “underwriter,” the Company shall use its commercially reasonable efforts to persuade the Commission that the offering contemplated by such Registration Statement is a valid secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 and that the Purchaser is not an “underwriter.” The Purchaser shall have the right to review and oversee any registration or matters pursuant to this Section 4.15, including any participation in meetings or discussions with the Commission regarding the Commission’s position and to comment on any written submission made to the Commission with respect thereto. In the event that, despite the Company’s commercially reasonable efforts and compliance with the terms of this Section 4.15, the Staff refuses to alter its position, the Company shall (A) remove from the Registration Statement such portion of the Registrable Shares (the “Cut Back Shares”) and/or (B) agree to such restrictions and limitations on the registration of the Registrable Shares as the Commission may require to assure the Company’s compliance with the requirements of Rule 415 (collectively, the “SEC Restrictions”); provided, however, that the Company shall not agree to name the Purchaser as an “underwriter” in such Registration Statement without the prior written consent of the Purchaser. No damages shall accrue as to any Cut Back Shares until such date as the Company is able to effect the registration of such Cut Back Shares in accordance with any SEC Restrictions (such date, the “Restriction Termination Date” of such Cut Back Shares). From and after the Restriction Termination Date applicable to any Cut Back Shares, all of the provisions of this Section 4.15 shall again be applicable to such Cut Back

28

Shares; provided, however, that (x) the filing deadline for the Registration Statement including such Cut Back Shares shall be ten (10) Trading Days after such Restriction Termination Date, and (y) the Effectiveness Deadline with respect to such Cut Back Shares shall be the 90th day immediately after the Restriction Termination Date or the 120th day if the Staff reviews such Registration Statement (but in any event no later than three (3) Trading Days from the Staff indicating it has no further comments on such Registration Statement).

(d) Secondary Piggyback Registration. Subject to the terms and conditions hereof, and solely with respect to any Conversion Shares for which, at the relevant time, no Registration Statement is effective, whenever the Company proposes to file a registration statement under the Securities Act for the purpose of registering the equity securities of any third party, whether or not such registration statement includes the registration of shares for its own account (a “Secondary Piggyback Registration”), the Company shall give the Purchaser prompt written notice thereof (but not less than ten (10) Business Days prior to the filing by the Company with the Commission of any registration statement with respect thereto or, in the case of an offering of equity securities from an existing registration statement, prior to the anticipated pricing date). Such notice (a “Piggyback Notice”) shall specify, at a minimum, the number of equity securities proposed to be registered, the proposed date of filing of such registration statement with the Commission (or anticipated date of pricing, as applicable), the proposed means of distribution, the proposed managing underwriter or underwriters (if any and if known) and a good faith estimate by the Company of the proposed minimum offering price of such equity securities. Upon the written request of the Purchaser, which such written request shall specify the number of Registrable Shares then presently intended to be disposed of by the Purchaser, given within five (5) Business Days after such Piggyback Notice is received by the Purchaser, the Company, subject to the terms and conditions of this Agreement, shall use its best efforts to cause all such Registrable Shares held by the Purchaser with respect to which the Company has received such written requests for inclusion to be included in such Secondary Piggyback Registration on the same terms and conditions as the other third-party equity securities being sold in such Secondary Piggyback Registration.

(e) Registration and Offering Expenses. All Sale Expenses (as defined below) incurred in connection with Section 4.15(a) and Section 4.15(f) shall be borne by the Company. “Sale Expenses” shall mean (a) the fees and disbursements of counsel of the Company and independent public accountants for the Company incurred in connection with the Registration Statement or Secondary Piggyback Registration, including the expenses of any special audits or “comfort” letters required by any such Secondary Piggyback Registration, and (b) all registration, filing and stock exchange fees, all fees and expenses of complying with securities or “blue sky” laws (including any legal investment memoranda related thereto), all fees and expenses of custodians, transfer agents and registrars, all printing and producing expenses, provided, however, that “Sale Expenses” shall not include any out-of-pocket expenses of the Purchaser or any transfer taxes, underwriting or brokerage commissions or discounts associated with effecting those sales of Registrable Shares that may be offered by the Purchaser, which expenses shall be borne by the Purchaser.

(f) Indemnification.

(i) The Company agrees to indemnify and hold harmless each Purchaser Party, to the fullest extent permitted by applicable law, from and against any losses, claims, damages or liabilities (collectively, “Losses”), joint or several, to which they may become subject (under the Securities Act or otherwise) insofar as such Losses (or actions or proceedings in respect thereof) arise out of, or are based upon, any untrue or alleged untrue statement of a material fact contained in the Registration Statement or any omission or alleged omission to state a material fact required to be stated in the prospectus contained therein or necessary to make the statements in the prospectus contained therein, in light of the circumstances under which they were made, not misleading or arise out of any failure by the Company to fulfill any undertaking included in the Registration Statement and the Company will, as incurred, reimburse the Purchaser Parties for any reasonable and documented legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that the Company shall not be liable in any such case to the extent that such Loss arises out of, or is based upon an untrue statement or omission made in such Registration Statement in reliance upon and in

29

conformity with written information furnished to the Company by or on behalf of the Purchaser specifically for inclusion in the Registration Statement; provided further, however, that the Company shall not be liable to any Purchaser Party (or any partner, member, officer, director or controlling Person of the Purchaser) to the extent that any such Loss is caused by an untrue statement or omission made in any preliminary prospectus if either (1) (a) the Purchaser failed to send or deliver a copy of the final prospectus with or prior to, or the Purchaser failed to confirm that a final prospectus was deemed to be delivered prior to (in accordance with Rule 172 of the Securities Act), the delivery of written confirmation of the sale by the Purchaser to the Person asserting the claim from which such Loss resulted and (b) the final prospectus corrected such untrue statement or omission, (2) (x) such untrue statement or omission is corrected in an amendment or supplement to the prospectus and (y) having previously been furnished by or on behalf of the Company with copies of the prospectus as so amended or supplemented or notified by the Company that such amended or supplemented prospectus has been filed with the Commission, in accordance with Rule 172 of the Securities Act, the Purchaser thereafter fails to deliver such prospectus as so amended or supplemented, with or prior to or a Purchaser fails to confirm that the prospectus as so amended or supplemented was deemed to be delivered prior to (in accordance with Rule 172 of the Securities Act), the delivery of written confirmation of the sale by the Purchaser to the Person asserting the claim from which such Loss resulted or (3) the Purchaser sold Registrable Shares in violation of the Purchaser’s covenants contained in Article IV of this Agreement.

(ii) The Purchaser agrees to indemnify and hold harmless the Company and its officers, directors, employees, affiliates, agents and representatives and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each a “Company Party” and collectively the “Company Parties”), from and against any Losses to which the Company Parties may become subject (under the Securities Act or otherwise), insofar as such Losses (or actions or proceedings in respect thereof) arise out of, or are based upon, any untrue statement of a material fact contained in the Registration Statement (or any omission to state therein 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 in each case, on the effective date thereof), if, and only to the extent, such untrue statement or omission was made in reliance upon and in conformity with written information furnished by or on behalf of the Purchaser specifically for inclusion in the Registration Statement, and the Purchaser will reimburse each Company Party for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that in no event shall any indemnity under this Section 4.15(f)(ii) be greater in amount than the dollar amount of the proceeds (net of all expenses paid by the Purchaser in connection with any claim relating to this Section 4.15 and the amount of any damages the Purchaser has otherwise been required to pay by reason of such untrue statement or omission) received by the Purchaser upon its sale of the Registrable Shares included in the Registration Statement giving rise to such indemnification obligation.

(iii) Promptly after receipt by any indemnified Person of a notice of a claim or the beginning of any action in respect of which indemnity is to be sought against an indemnifying Person pursuant to this Section 4.15(f), such indemnified Person shall notify the indemnifying Person in writing of such claim or of the commencement of such action, and, subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified Person and such indemnifying Person shall have been notified thereof, such indemnifying Person shall be entitled to participate therein, and, to the extent that it shall wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified Person. After notice from the indemnifying Person to such indemnified Person of its election to assume the defense thereof, such indemnifying Person shall not be liable to such indemnified Person for any legal expenses subsequently incurred by such indemnified Person in connection with the defense thereof; provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate in the reasonable judgment of the indemnified Person for the same counsel to represent both the indemnified Person and such indemnifying Person or any affiliate or associate thereof, the indemnified Person shall be entitled to retain its own counsel at the expense of such indemnifying Person; provided, further, that no indemnifying Person shall be responsible for the fees and expense of more than one separate counsel for all indemnified parties. The indemnifying party shall not settle an action without the consent of the indemnified party, which consent shall not be unreasonably withheld.

30

(iv) If after proper notice of a claim or the commencement of any action against the indemnified party, the indemnifying party does not choose to participate, then the indemnified party shall assume the defense thereof and upon written notice by the indemnified party requesting advance payment of a stated amount for its reasonable defense costs and expenses, the indemnifying party shall advance payment for such reasonable defense costs and expenses (the “Advance Indemnification Payment”) to the indemnified party. In the event that the indemnified party’s actual defense costs and expenses exceed the amount of the Advance Indemnification Payment, then upon written request by the indemnified party, the indemnifying party shall reimburse the indemnified party for such difference; in the event that the Advance Indemnification Payment exceeds the indemnified party’s actual costs and expenses, the indemnified party shall promptly remit payment of such difference to the indemnifying party.

(v) If the indemnification provided for in this Section 4.15(f) is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other, as well as any other relevant equitable considerations; provided, that in no event shall any contribution by the Purchaser hereunder be greater in amount than the dollar amount of the proceeds received by the Purchaser upon the sale of such Registrable Shares. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the Securities Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation.

(g) Prospectus Suspension. The Purchaser acknowledges that there may be times when the Company must suspend the use of the prospectus forming a part of a Registration Statement until such time as an amendment to such Registration Statement has been filed by the Company and declared effective by the Commission, or until such time as the Company has filed an appropriate report with the Commission pursuant to the Exchange Act. The Purchaser hereby covenants that it will not sell any Registrable Shares pursuant to said prospectus during the period commencing at the time at which the Company gives the Purchaser notice of the suspension of the use of said prospectus and ending at the time the Company gives the Purchaser notice that the Purchaser may thereafter effect sales pursuant to said prospectus; provided, that such suspension periods shall in no event exceed thirty (30) consecutive calendar days or a total of sixty (60) calendar days (which need not be consecutive calendar days) in any 12-month period and that, in the good faith judgment of the Company’s Board of Directors, the Company would, in the absence of such delay or suspension hereunder, be required under state or federal securities laws to disclose any corporate development, a potentially significant transaction or event involving the Company, or any negotiations, discussions, or proposals directly relating thereto, in either case the disclosure of which would reasonably be expected to have a Material Adverse Effect upon the Company or its stockholders.

(h) Termination of Obligations. The obligations of the Company pursuant to Section 4.15(a) hereof shall cease and terminate, with respect to any Registrable Shares, upon the earlier to occur of (i) such time such Registrable Shares have been resold, or (ii) such time as such Shares no longer remain Registrable Shares.

(i) Reporting Requirements. With a view to making available the benefits of certain rules and regulations of the Commission that may at any time permit the sale of the Registrable Shares to the public without registration or pursuant to a registration statement on Form S-3, the Company agrees to:

(i) make and keep public information available, as those terms are understood and defined in Rule 144; and

(ii) so long as the Purchaser owns Registrable Shares, to furnish to the Purchaser upon request (A) a written statement by the Company as to whether it is in compliance with the reporting requirements of Rule 144 and the Exchange Act, or whether it is qualified as a registrant whose securities may be resold pursuant to Form S-3 and (B) such other information as may be reasonably requested to permit the Purchaser to sell such securities pursuant to Rule 144.

31

4.16 Rights of First Negotiation. During the ROFN Initiation Period (as defined in Exhibit B), the Purchaser shall have the rights of first negotiation with respect to the matters, and subject to the terms and conditions, set forth in Exhibit B attached hereto.

4.17 Confidentiality.

(a) Confidential Information. “Confidential Information” means, subject to the exceptions set out in Section 4.17(c) below, any non-public information or materials furnished by or on behalf of one party hereto or any of its Affiliates (together, the “Disclosing Party”) to the other party hereto or any of its Affiliates (together, the “Receiving Party”) pursuant to or in connection with the Transaction Documents and the transactions between the Company and the Purchaser contemplated hereby or thereby, whether on electronic or hard copy media or orally, including any and all data, analyses, compilations, studies, reports or other documents relating to such information prepared by the Disclosing Party or its Representatives and provided or made accessible by the Disclosing Party to the Receiving Party. Notwithstanding the foregoing definition, the parties hereto agree that the following information shall constitute Confidential Information of the Company (without regard to which party initially disclosed such information to the other party): (i) any information or materials provided pursuant to Section 8 or 9 of the ROFN; (ii) any materials or information provided pursuant to Section 4.7 or Section 4.14; and (iii) all communications or correspondence delivered by or on behalf of the Company pursuant to or in connection with the Transaction Documents and the transactions between the Company and the Purchaser contemplated hereby or thereby, including the fact that such communications or correspondence relate to the Transaction Documents or the transactions between the Company and the Purchaser contemplated hereby or thereby. Further, the parties hereto agree that any confidential information provided by or on behalf of one party to the other party pursuant to the Confidentiality Agreement between the Company and Sanofi dated November 30, 2023 shall also be deemed to be Confidential Information of the party that disclosed the relevant information for the purposes of this Agreement (and regardless of the exceptions set out in Section 4.17(b)(i)).

(b) Exceptions. Confidential Information shall not include any information to the extent such information: (i) is already known by the Receiving Party or its Representatives at the time such information was received or accessed, and the Receiving Party has evidence to demonstrate such prior knowledge, provided that information shall not be “already known” for the purposes of this clause (i) if such information was received by the Receiving Party from the Disclosing Party on a confidential basis prior to the date of this Agreement; (ii) is or becomes publicly known without breach of this Agreement by the Receiving Party or any of its Representatives; (iii) is or becomes available to the Receiving Party or its Representatives on a non-confidential basis from an independent third party not bound by an obligation of secrecy to the Disclosing Party with respect to such information; or (iv) is independently developed by or on behalf of the Receiving Party or its Representatives without reliance on or use of the Confidential Information, and the Receiving Party has evidence to demonstrate such independent development.

(c) Obligations of Confidentiality and Non-Use. For a period of six (6) years commencing on the Closing Date (the “Term”):

(i) Each Disclosing Party may disclose to each Receiving Party such Confidential Information as such Disclosing Party deems necessary and desirable in connection with the Transaction Documents and the transactions between the Company and the Purchaser contemplated hereby and thereby; provided, however, that (x) no Prior Consent Information will be disclosed by any Disclosing Party to any Receiving Party without the prior written consent of such Receiving Party, and (y) any Prior Consent Information disclosed in violation of the foregoing clause (x) will not be deemed to be Confidential Information hereunder. For clarity, Purchaser shall be deemed to have consented to receive any Prior Consent Information included in the materials provided by the Company pursuant to Section 4.7 and Section 4.14 of this Agreement or as expressly contemplated under the ROFN.

32

(ii) Except as otherwise permitted pursuant to the Transaction Documents, all Confidential Information of a Disclosing Party must be maintained in confidence by the Receiving Party, must not be disclosed to any third party, and must be protected with the same degree of care the Receiving Party normally uses in the protection of its own confidential and proprietary information, but in no case with any less degree than reasonable care.

(iii) Except as otherwise expressly provided in this Section 4.17, pursuant to the Transaction Documents, Confidential Information of a Disclosing Party may be disclosed by a Receiving Party only to Representatives of the Receiving Party having a reasonable need to receive such Confidential Information for the purposes of the Receiving Party exercising its rights or performing its obligations in accordance with the Transaction Documents or the transactions between the Company and the Purchaser contemplated hereby and thereby (the “Permitted Purposes”), provided that each such recipient is bound by confidentiality and non-use obligations substantially similar to those undertaken by the Receiving Party under this Agreement.

(iv) The Receiving Party must not use or disclose any Confidential Information of the Disclosing Party for any purpose other than the Permitted Purposes.

(v) The Receiving Party must not copy, reproduce, or reduce to writing any part of the Confidential Information of the Disclosing Party, except as is reasonably necessary for the Permitted Purposes.

(vi) Upon expiration of the Term, the Receiving Party (i) must cease to use the Confidential Information, and (ii) within sixty (60) days after the date of a written notice by the Disclosing Party, must use all reasonable efforts to destroy all copies thereof then in its possession or control; except that, the Receiving Party (x) may retain access to the Confidential Information, for the purpose of establishing the scope and contents of the documents received under the Transaction Documents and for the purpose of providing legal advice with regard to compliance with the Transaction Documents, and (y) will not be required to destroy any computer files stored securely by it that are created during automatic system back-up or that are kept for regulatory purposes or that are otherwise impracticable to destroy.

(d) Authorized Disclosure. The Receiving Party may disclose Confidential Information if required to disclose information by applicable law, regulation, court order or regulatory process reasonably connected to the transactions contemplated by the Transaction Documents or otherwise; provided, however, that, if legally permissible and to the extent reasonably practicable, the Receiving Party shall immediately notify (or, if the nature of such disclosure precludes immediate notification, notify as soon as possible under the circumstances) the Disclosing Party in writing of such requirement or court order and shall reasonably cooperate with the Disclosing Party, at the Disclosing Party’s sole expense, to limit the extent of any such disclosure. Notwithstanding the foregoing, if such relief from disclosure has not been obtained and the Receiving Party is, in the view of its counsel (which may include internal counsel), nonetheless required to disclose Confidential Information of the Disclosing Party, the Receiving Party shall be permitted to disclose such Confidential Information solely as is reasonably necessary to satisfy such legal requirements.

(e) Acknowledgements. Each party hereto acknowledges and agrees that each party and its Affiliates (i) conduct research, development, manufacturing, and marketing programs and businesses that may be competitive with the other party’s business (the “Competitive Programs”), (ii) manufacture, market, sell and distribute, and may develop, products and compounds that may be competitive with products and compounds related to the other party’s business (the “Competitive Products”), and (iii) now possess, or may receive or independently develop information and other materials that are similar to the Confidential Information disclosed by or on behalf of the Disclosing Party to the Receiving Party (the “Similar Information”). Expect as provided and without limiting Section 10 of the ROFN, nothing in this Agreement shall be construed to preclude each party and its Affiliates from (I) conducting the Competitive Programs, (II) manufacturing, marketing, selling, distributing or developing the Competitive Products, (III) using or in any way exploiting the Similar Information, or (IV) assigning any Representative who has been privy to the other party’s Confidential Information to perform work on the Competitive Programs or in connection with the Competitive Products; provided that, each of (I), (II), (III) and (IV) does not rely on or use the other party’s Confidential Information and the Receiving Party otherwise complies with its

33

obligations under the Transaction Documents with respect to the other party’s Confidential Information. Each party further acknowledges that its breach of this Section 4.17 may cause damage to the other party for which there may be no adequate remedy at law and hereby agrees that, in the event of such a breach or threatened breach, such other party is entitled to seek, in addition to any other remedies it may have at law or in equity, a restraining order, injunction or other similar remedy in order to specifically enforce this Section 4.17, as and to the extent permitted pursuant to applicable laws.

(a) Representations and Warranties. The representations and warranties made by the Company in Section 3.1 hereof shall be true and correct in all material respects (except for those representations and warranties which are qualified as to materiality, in which case such representations and warranties shall be true and correct in all respects) as of the date when made and as of the Closing Date, as though made on and as of such date, except for such representations and warranties that speak as of a specific date.

Each party agrees that all Proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective Affiliates, employees or agents) shall be commenced exclusively in the courts of the State of New York or into the Federal Court located in New York, New York. Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the courts of the State of New York or into the Federal Court located in New York, New York for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Proceeding, any claim that it is not personally subject to the jurisdiction of the aforesaid courts, or that such Proceeding has been commenced in an improper or inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law.

Delivery of an executed Agreement by one party to the other may be made by facsimile, electronic mail (including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

37

6.11 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

6.12 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever the Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then the Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

6.13 Replacement of Securities. If any certificate or instrument evidencing any Securities, if applicable, is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company and the Transfer Agent, as applicable, of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold harmless the Company and the Transfer Agent for any losses in connection therewith or, if required by the Transfer Agent, a bond in such form and amount as is required by the Transfer Agent. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities. If a replacement certificate or instrument evidencing any Securities is requested due to a mutilation thereof, the Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement.

6.14 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, the Purchaser and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agree to waive in any action for specific performance of any such obligation (other than in connection with any action for a temporary restraining order) the defense that a remedy at law would be adequate.

6.15 Payment Set Aside. To the extent that the Company makes a payment or payments to the Purchaser pursuant to any Transaction Document or the Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

6.16 Adjustments in Share Numbers and Prices. In the event of any stock split, subdivision, dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar recapitalization or event occurring after the date hereof and prior to the Closing, each reference in any Transaction Document to a number of shares or a price per share shall be deemed to be amended to appropriately account for such event.

6.17 Termination. This Agreement may be terminated and the sale and purchase of the Shares abandoned at any time prior to the Closing by either the Company or the Purchaser upon written notice to the other, if the Closing has not been consummated on or prior to 5:00 P.M., New York City time, on the Outside Date; provided, however, that the right to terminate this Agreement under this Section 6.17 shall not be available to any Person whose failure to comply with its obligations under this Agreement has been

38

the cause of or resulted in the failure of the Closing to occur on or before such time. Nothing in this Section 6.17 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other Transaction Documents. Upon a termination in accordance with this Section 6.17, the Company and the Purchaser shall not have any further obligation or liability (including arising from such termination) to the other.
