(b) Form S-3 Demand. If at any time when it is eligible to use a Form S-3 registration statement, the Company receives a request from Holders of at least ten percent (10%) of the Registrable Securities then outstanding that the Company file a Form S-3 registration statement with respect to outstanding Registrable Securities of such Holders having an anticipated aggregate offering price, net of Selling Expenses, of at least $5 million, then the Company shall (i) within ten (10) days after the date such request is given, give a Demand Notice to all Holders other than the Initiating Holders and (ii) as soon as practicable, and in any event within forty-five (45) days after the date such request is given by the Initiating Holders, file a Form S-3 registration statement under the Securities Act covering all Registrable Securities requested to be included in such registration by any other Holders, as specified by notice given by each such Holder to the Company within twenty (20) days of the date the Demand Notice is given, and in each case, subject to the limitations of Sections 2.1(c) and 2.3.

(c) Notwithstanding the foregoing obligations, if the Company furnishes to Holders requesting a registration pursuant to this Section 2.1 a certificate signed by the Company’s chief executive officer stating that in the good faith judgment of the Board it would be materially detrimental to the Company and its stockholders for such registration statement to either become effective or remain effective, then the Company shall have the right to defer taking action with respect to such filing, and any time periods with respect to filing or effectiveness thereof shall be tolled correspondingly, for a period of not more than sixty (60) days after the request of the Initiating Holders is given; provided, however, that the Company may not invoke this right more than twice in any twelve (12) month period (which may be for consecutive sixty (60) day periods aggregating to one hundred twenty (120) days); and provided further that the Company shall not register any securities or instruments for its own account or that of any other stockholder during such period other than an Excluded Registration.

(d) The Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to Section 2.1(a) (i) during the period that is sixty (60) days before the Company’s good faith estimate of the date of filing of, and ending on a date that is one hundred eighty (180) days after the effective date of, a Company-initiated registration, provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective; (ii) after the Company has effected two registrations pursuant to Section 2.1(a) or (iii) if the Initiating Holders propose to dispose of shares of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request

made pursuant to Section 2.1(b). The Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to Section 2.1(b) (A) during the period that is thirty (30) days before the Company’s good faith estimate of the date of filing of, and ending on a date that is ninety (90) days after the effective date of, a Company-initiated registration, provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective or (B) if the Company has effected two registrations pursuant to Section 2.1(b) within the twelve (12) month period immediately preceding the date of such request. A registration shall not be counted as “effected” for purposes of this Section 2.1(d) until such time as the applicable registration statement has been declared effective by the SEC, unless the Initiating Holders withdraw their request for such registration, elect not to pay the registration expenses therefor, and forfeit their right to one demand registration statement pursuant to Section 2.6, in which case such withdrawn registration statement shall be counted as “effected” for purposes of this Section 2.1(d).

2.2 Piggyback Registration Rights. If the Company proposes to register (including, for this purpose, a registration effected by the Company for stockholders other than the Holders) any of its Common Stock under the Securities Act in connection with the public offering of such securities solely for cash (other than in the IPO or an Excluded Registration), the Company shall, at such time, promptly give each Holder notice of such registration. Upon the request of each Holder given within twenty (20) days after such notice is given by the Company, the Company shall, subject to the provisions of Section 2.3, cause to be registered all of the Registrable Securities that each such Holder has requested to be included in such registration, provided, however, that a Stockholder may not invoke this right more than once in any twelve (12) month period. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2.2 before the effective date of such registration, whether or not any Holder has elected to include Registrable Securities in such registration. The expenses (other than Selling Expenses) of such withdrawn registration shall be borne by the Company in accordance with Section 2.6.

2.3 Underwriting Requirements.

(a) If, pursuant to Section 2.1, the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Section 2.1, and the Company shall include such information in the Demand Notice. The underwriter(s) will be selected by the Company and shall be reasonably acceptable to a majority in interest of the Initiating Holders. In such event, the right of any Holder to include such Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in Section 2.4(e)) enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting. Notwithstanding any other provision of this Section 2.3, if the underwriter(s) advise(s) the Initiating Holders in writing that marketing factors require a limitation on the number of shares to be underwritten, then the Initiating Holders shall so advise all Holders of Registrable Securities that otherwise would be underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be allocated among such Holders of Registrable Securities, including the

Initiating Holders, in proportion (as nearly as practicable) to the number of Registrable Securities owned by each Holder or in such other proportion as shall mutually be agreed to by all such selling Holders; provided, however, that the number of Registrable Securities held by the Holders to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares.

(b) In connection with any offering involving an underwriting of shares of the Company’s capital stock pursuant to Section 2.2, the Company shall not be required to include any of the Holders’ Registrable Securities in such underwriting unless the Holders accept the terms of the underwriting as agreed upon between the Company and its underwriters, and then only in such quantity as the underwriters in their sole discretion determine will not jeopardize the success of the offering by the Company. If the total number of securities, including Registrable Securities, requested by Stockholders to be included in such offering exceeds the number of securities to be sold (other than by the Company) that the underwriters in their reasonable discretion determine is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters and the Company in their sole discretion determine will not jeopardize the success of the offering. If the underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the Registrable Securities that are included in such offering shall be allocated among the selling Holders in proportion (as nearly as practicable to) the number of Registrable Securities owned by each selling Holder or in such other proportions as shall mutually be agreed to by all such selling Holders. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. Notwithstanding the foregoing, in no event shall (i) the number of Registrable Securities included in the offering be reduced unless all other securities (other than securities to be sold by the Company) are first entirely excluded from the offering or (ii) the number of Registrable Securities included in the offering be reduced below twenty percent (20%) of the total number of securities included in such offering, unless such offering is the IPO, in which case the selling Holders may be excluded further if the underwriters make the determination described above and no other stockholder’s securities are included in such offering. For purposes of the provision in this Section 2.3(b) concerning apportionment, for any selling Holder that is a partnership, limited liability company or corporation, the partners, members, retired partners, retired members, Stockholders, and Affiliates of such Holder, or the estates and Immediate Family Members of any such partners, retired partners, members and retired members, and any trusts for the benefit of any of the foregoing Persons, shall be deemed to be a single “selling Holder,” and any pro rata reduction with respect to such “selling Holder” shall be based upon the aggregate number of Registrable Securities owned by all Persons included in such “selling Holder,” as defined in this sentence.

(c) For purposes of Section 2.1, a registration shall not be counted as “effected” if, as a result of an exercise of the underwriter’s cutback provisions in Section 2.3(a), fewer than fifty percent (50%) of the total number of Registrable Securities that Holders have requested to be included in such registration statement are actually included.

2.4 Obligations of the Company. Whenever required under this Section 2 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible:

(a) prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such registration statement to become effective and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to one hundred twenty (120) days or, if earlier, until the distribution contemplated in the registration statement has been completed; provided, however, that (i) such one hundred twenty (120) day period shall be extended for a period of time equal to the period the Holder refrains, at the request of an underwriter of Common Stock (or other securities) of the Company, from selling any securities included in such registration and (ii) in the case of any registration of Registrable Securities on Form S-3 that are intended to be offered on a continuous or delayed basis, subject to compliance with applicable SEC rules, such one hundred twenty (120) day period shall be extended for up to two hundred forty (240) days, if necessary, to keep the registration statement effective until all such Registrable Securities are sold;

(b) prepare and file with the SEC such amendments and supplements to such registration statement, and the prospectus used in connection with such registration statement, as may be necessary to comply with the Securities Act in order to enable the disposition of all securities covered by such registration statement;

(c) furnish to the selling Holders such numbers of copies of a prospectus, including a preliminary prospectus, as required by the Securities Act, and such other documents as the Holders may reasonably request in order to facilitate their disposition of their Registrable Securities;

(d) use its commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or blue-sky laws of such jurisdictions as shall be reasonably requested by the selling Holders; provided that the Company shall not be required to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act;

(e) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the underwriter(s) of such offering;

(f) use its commercially reasonable efforts to cause all such Registrable Securities covered by such registration statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities issued by the Company are then listed;

(g) provide a transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and provide a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration;

(h) promptly make available for inspection by the selling Holders, any managing underwriter(s) participating in any disposition pursuant to such registration statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling Holders, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent, in each case, as necessary or advisable to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith;

(i) notify each selling Holder, promptly after the Company receives notice thereof, of the time when such registration statement has been declared effective or a supplement to any prospectus forming a part of such registration statement has been filed; and

(j) after such registration statement becomes effective, notify each selling Holder of any request by the SEC that the Company amend or supplement such registration statement or prospectus.

In addition, the Company shall ensure that, at all times after any registration statement covering a public offering of securities of the Company under the Securities Act shall have become effective, its xxxxxxx xxxxxxx policy shall provide that the Company’s directors may implement a trading program under Rule 10b5-1 of the Exchange Act.

2.5 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 2 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as is reasonably required to effect the registration of such Holder’s Registrable Securities.

(c) Promptly after receipt by an indemnified party under this Section 2.8 of notice of the commencement of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.8, give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in such action and, to the extent the indemnifying party so desires, participate jointly with any other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such action. The failure to give notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.8, to the extent that such failure materially prejudices the indemnifying party’s ability to defend such action. The failure to give notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.8.

(d) To provide for just and equitable contribution to joint liability under the Securities Act in any case in which either: (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Section 2.8 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that this Section 2.8 provides for indemnification in such case or (ii) contribution under the Securities Act may be required on the part of any party hereto for which indemnification is provided under this Section 2.8, then, and in each such case, such parties will contribute to the aggregate losses, claims, damages, liabilities or expenses to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions or other actions that resulted in such loss, claim, damage, liability or expense, as well as to reflect any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact, or the omission or alleged omission of a material fact, relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, however, that, in any such case (A) no Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such Holder pursuant to such registration statement and (B) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and provided further that in no event shall a Holder’s liability pursuant to this Section 2.8(d), when combined with the amounts paid or payable by such Holder pursuant to Section 2.8(b), exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of willful misconduct or fraud by such Holder.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

(f) Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public offering, the obligations of the Company and Holders under this Section 2.8 shall survive the completion of any offering of Registrable Securities in a registration under this Section 2, and otherwise shall survive the termination of this Agreement.

2.9 Reports Under Exchange Act. With a view to making available to the Holders the benefits of SEC Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company shall:

(a) make and keep available adequate current public information, as those terms are understood and defined in SEC Rule 144, at all times after the effective date of the registration statement filed by the Company for the IPO;

(b) use commercially reasonable efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after the Company has become subject to such reporting requirements); and

(c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) to the extent accurate, a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after ninety (90) days after the effective date of the registration statement filed by the Company for the IPO), the Securities Act and the Exchange Act (at any time after the Company has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after the Company so qualifies); and (ii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any such securities without registration (at any time after the Company has become subject to the reporting requirements under the Exchange Act) or pursuant to Form S-3 (at any time after the Company so qualifies to use such form).

2.10 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of (i) prior to the IPO, the Holders holding a majority of the shares of Series D Convertible Preferred Stock then held by the Holders or (ii) following the IPO, the Holders holding a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective holder of any securities of the Company that allow such holder or prospective holder (a) to include such securities in any registration unless, under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of such securities will not reduce the number of the Registrable Securities of the Holders that are included or (b) allow such holder or prospective holder to initiate a demand for registration of any securities held by such holder or prospective holder; provided that this limitation shall not apply to any Additional Stockholder.

2.11 “Market Stand-off” Agreement. Each Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating to the registration by the Company for its own behalf of shares of its Common Stock or any other equity securities under the Securities Act on a registration statement on Form S-1 or Form S-3 in an underwritten offering, and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days), (i) Transfer, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Stock owned by such Holder as of the date of the IPO or (ii) enter into any swap or other arrangement that Transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise. The foregoing provisions of this Section 2.11 shall apply only to the IPO, shall be applicable to the Holders only if all officers, directors and Stockholders owning at least 1% of the Common Stock on an as-converted basis are subject to the same restrictions, and shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, or the Transfer of any shares to any trust for the direct or indirect benefit of the Holder or the immediate family of the Holder, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such Transfer shall not involve a disposition for value. The underwriters in connection with such registration are intended third-party beneficiaries of this Section 2.11 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in connection with such registration that are consistent with this Section 2.11 or that are necessary to give further effect thereto. Any discretionary waiver or termination of the restrictions set forth herein or in any agreement described in the preceding sentence shall be promptly disclosed in writing by the Company to all Holders, and shall be deemed to apply to all such agreements on a pro rata basis based on the numbers of shares of Common Stock held by the Holders party to such agreements on an as-converted basis.

2.12 Termination of Registration Rights. The right of any Holder to request registration or inclusion of Registrable Securities in any registration pursuant to Sections 2.1 or 2.2 shall terminate upon the earliest to occur of:

(a) the closing of a Sale of the Company;

(b) such time as SEC Rule 144 or another similar exemption under the Securities Act is available for the sale of all of such Holder’s shares without limitation during a three-month period without registration, except that the termination of registration rights set forth in this Section 2.12(b) shall not apply to any Holder of Registrable Securities who is a director or executive officer of the Company; and

(v) to refrain from exercising any dissenters’ rights or rights of appraisal under applicable law at any time with respect to such Sale of the Company;

(vi) if the consideration to be paid in exchange for the Voting Securities pursuant to this Section 4.3 includes any securities and due receipt thereof by any Stockholder would require under applicable law (x) the registration or qualification of such securities or of any person as a broker or dealer or agent with respect to such securities; or (y) the provision to any Stockholder of any information other than such information as a prudent issuer would generally furnish in an offering made solely to “accredited investors” as defined in Regulation D promulgated under the Securities Act, the Company may cause to be paid to any such Stockholder in lieu thereof, against surrender of the Voting Securities which would have otherwise been sold by such Stockholder, an amount in cash equal to the fair value (as determined in good faith by the Company) of the securities which such Stockholder would otherwise receive as of the date of the issuance of such securities in exchange for the Voting Securities; and

(vii) in the event that the Selling Investors, in connection with such Sale of the Company, appoint a stockholder representative (the “Stockholder Representative”) with respect to matters affecting the Stockholders under the applicable definitive transaction agreements following consummation of such Sale of the Company, (x) to consent to (i) the appointment of such Stockholder Representative, (ii) the establishment of any applicable escrow, expense or similar fund in connection with any indemnification or similar obligations, and (iii) the payment of such Stockholder’s pro rata portion (from the applicable escrow or expense fund or otherwise) of any and all reasonable fees and expenses to such Stockholder Representative in connection with such Stockholder Representative’s services and duties in connection with such Sale of the Company and its related service as the representative of the Stockholders, and (y) not to assert any claim or commence any suit against the Stockholder Representative or any other Stockholder with respect to any action or inaction taken or failed to be taken by the Stockholder Representative in connection with its service as the Stockholder Representative, absent fraud or willful misconduct.

(b) Exceptions. Notwithstanding the foregoing, a Stockholder will not be required to comply with Section 4.3(a) above in connection with any proposed Sale of the Company (the “Proposed Sale”), unless:

(i) any representations and warranties to be made by such Stockholder in connection with the Proposed Sale are limited to representations and warranties related to authority, ownership and the ability to convey title to such Shares, including, but not limited to, representations and warranties that (a) the Stockholder holds all right, title and interest in and to the Shares such Stockholder purports to hold, free and clear of all liens and encumbrances, (b) the obligations of the Stockholder in connection with the transaction have been duly authorized, if applicable, (c) the documents to be entered into by the Stockholder have been duly executed by the Stockholder and delivered to the acquirer and are enforceable against the Stockholder in accordance with their respective terms, and (d) neither the execution and delivery of documents to be entered into in connection with the transaction, nor the performance of the Stockholder’s obligations thereunder, will cause a breach or violation of the terms of any agreement, law or judgment, order or decree of any court or governmental agency;

(ii) such Stockholder shall not be liable for the inaccuracy of any representation or warranty made by any other Person in connection with the Proposed Sale, other than the Company (except to the extent that funds may be paid out of an escrow established to cover breach of representations, warranties and covenants of the Company as well as breach by any stockholder of any of identical representations, warranties and covenants provided by all stockholders);

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

(iv) upon the consummation of the Proposed Sale (i) each holder of each class or series of the Company’s stock will receive the same form of consideration for their shares of such class or series as is received by other holders in respect of their shares of such same class or series of stock, (ii) each holder of a series of Preferred Stock will receive the same amount of consideration per share of such series of Preferred Stock as is received by other holders in respect of their shares of such same series, (iii) each holder of Common Stock will receive the same amount of consideration per share of Common Stock as is received by other holders in respect of their shares of Common Stock, and (iv) unless the holders of a majority of the shares of Common Stock then issued or issuable upon conversion of the shares of Preferred Stock (to include the holders of a majority of the shares of Common Stock then issued or issuable upon conversion of the shares of Series D Convertible Preferred Stock) elect to receive a lesser amount by written notice given to the Company at least ten (10) days prior to the effective date of any such Proposed Sale, the aggregate consideration receivable by all holders of the Preferred Stock and Common Stock shall be allocated among the holders of Preferred Stock and Common Stock on the basis of the relative liquidation preferences to which the holders of each respective series of Preferred Stock and the holders of Common Stock are entitled in a Deemed Liquidation Event (assuming for this purpose that the Proposed Sale is a Deemed Liquidation Event) in accordance with the Company’s Certificate of Incorporation in effect immediately prior to the Proposed Sale; provided, however, that, notwithstanding the foregoing, if the consideration to be paid in exchange for the Key Holder Voting Securities or Preferred Stock, as applicable, pursuant to this Section 4.3(b)(iv) includes any securities and due receipt thereof by any Key Holder or holder of Preferred Stock would require under applicable law (x) the registration or qualification of such securities or of any person as a broker or dealer or agent with respect to such securities; or (y) the provision to any Key Holder or holder of Preferred Stock of any information other than such information as a prudent issuer would generally furnish in an offering made solely to “accredited investors” as defined in Regulation D promulgated under the Securities Act, the Company may cause to be paid to any such Key Holder or holder of Preferred Stock in lieu thereof, against surrender of the Key Holder Voting Securities or Preferred Stock, as applicable, which would have otherwise been sold by such Key Holder or holder of Preferred Stock, an amount in cash equal to the fair value

(as determined in good faith by the Company) of the securities which such Key Holder or holder of Preferred Stock would otherwise receive as of the date of the issuance of such securities in exchange for the Key Holder Voting Securities or Preferred Stock, as applicable.

(c) Restrictions on Sales of Control of the Company. No Stockholder shall be a party to any Stock Sale unless all holders of Preferred Stock are allowed to participate in such transaction and the consideration received pursuant to such transaction is allocated among the parties thereto in the manner specified in the Company’s Certificate of Incorporation in effect immediately prior to the Stock Sale (as if such transaction were a Deemed Liquidation Event), unless the holders of a majority in voting power of the Preferred Stock then outstanding and the holders of a majority of the Series D Convertible Preferred Stock then outstanding elect otherwise by written notice given to the Company at least 10 days prior to the effective date of any such transaction or series of related transactions.

4.4 Termination of Voting Rights. The covenants set forth in this Section 4 shall terminate and be of no further force and effect (a) immediately before the consummation of the IPO, (b) when the Company first becomes subject to the periodic reporting requirements of Section 12(g) or 15(d) of the Exchange Act or (c) upon a Sale of the Company, whichever event occurs first.

5. Additional Covenants and Agreements.

5.1 Restrictions on Transfer.

(a) The Voting Securities shall not be Transferred, and the Company shall not recognize and shall issue stop-transfer instructions to its transfer agent with respect to any such Transfer, except upon the conditions specified in this Agreement, which conditions are intended to ensure compliance with the provisions of the Securities Act. A transferring Holder will cause any proposed transferee of the Voting Securities held by such Holder to agree to take and hold such Voting Securities subject to the provisions and upon the conditions specified in this Agreement.

(b) Each certificate or instrument representing the Voting Securities shall be stamped or otherwise imprinted with a legend substantially in the following form:

THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. SUCH SHARES MAY NOT BE SOLD, PLEDGED, OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR A VALID EXEMPTION FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SAID ACT.

THE SECURITIES REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF THE CENTREXION THERAPEUTICS CORPORATION THIRD AMENDED AND RESTATED STOCKHOLDERS AGREEMENT, DATED AS OF DECEMBER 18, 2017, AMONG THE COMPANY, EACH STOCKHOLDER PARTY THERETO, AS MAY BE AMENDED FROM TIME TO TIME, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

The Holders consent to the Company making a notation in its records and giving instructions to any transfer agent of the Voting Securities in order to implement the restrictions on Transfer set forth in this Section 5.1.

(c) The Holder of each certificate representing Voting Securities, by acceptance thereof, agrees to comply in all respects with the provisions of this Section 5.1. Before any proposed Transfer of any Voting Securities, unless there is in effect a registration statement under the Securities Act covering the proposed transaction, the Holder thereof shall give notice to the Company of such Holder’s intention to effect such Transfer. Each such notice shall describe the manner and circumstances of the proposed Transfer in sufficient detail and, if reasonably requested by the Company, shall be accompanied at such Holder’s expense by either (i) a written opinion of legal counsel who shall, and whose legal opinion shall, be reasonably satisfactory to the Company, addressed to the Company, to the effect that the proposed transaction may be effected without registration under the Securities Act, (ii) a “no action” letter from the SEC to the effect that the proposed Transfer of such Voting Securities without registration will not result in a recommendation by the staff of the SEC that action be taken with respect thereto or (iii) any other evidence reasonably satisfactory to counsel to the Company to the effect that the proposed Transfer of the Voting Securities may be effected without registration under the Securities Act, whereupon the Holder of such Voting Securities shall be entitled to Transfer such Voting Securities in accordance with the terms of the notice given by the Holder to the Company. The Company will not require such a legal opinion or “no action” letter (A) in any transaction in compliance with SEC Rule 144 or (B) in any transaction in which such Holder distributes Voting Securities to an Affiliate of such Holder for no consideration; provided that each transferee agrees in writing to be subject to the terms of this Section 5.1. Each certificate or instrument evidencing the Voting Securities Transferred as above provided shall bear, except if such Transfer is made pursuant to SEC Rule 144, the appropriate restrictive legend set forth in Section 5.1(b).

(d) None of the Stockholders may Transfer any shares of Common Stock or Preferred Stock to any Person that is not an “accredited investor,” as defined in Rule 501 under the Securities Act.

5.2 Tag-along Rights. If a Selling Stockholder proposes to sell any of its shares of Common Stock to an independent third party, the Stockholders that hold Series D Convertible Preferred Stock and Series C Convertible Preferred Stock shall be permitted to participate in such sale on the terms and conditions set forth in this Section 5.2.

(a) Prior to the consummation of the sale described above, the Selling Stockholder shall deliver to the Company and each other Holder a Sale Notice no more than ten (10) Business Days after the execution and delivery by all parties thereto of the definitive agreement entered into with respect to the sale, and, in any event, no later than twenty (20) Business Days prior to the closing date of the proposed sale. The Sale Notice shall make reference to the tag-along rights hereunder and shall describe in reasonable detail (i) the number of shares of Common Stock to be sold by the Selling Stockholder, (ii) the name of the Proposed Transferee; (iii) the per share purchase price and the other material terms and conditions of the sale, including a description of any non-cash consideration in sufficient detail to permit the valuation thereof; (iv) the proposed date, time and location of the closing of the sale; and (v) a copy of any form of agreement proposed to be executed in connection therewith.

(b) Shares to be Sold.

(i) Each Tag-along Stockholder shall exercise its right to participate in a sale of Common Stock by the Selling Stockholder subject to this Section 5.2 by delivering to the Selling Stockholder a Tag-along Notice stating its election to do so and specifying the number of shares of Common Stock to be sold by it no later than five Business Days after receipt of the Sale Notice. The offer of each Tag-along Stockholder set forth in a Tag-along Notice shall be irrevocable, and, to the extent such offer is accepted, such Tag-along Stockholder shall be bound and obligated to sell in the proposed sale on the terms and conditions set forth in this Section 5.2. Each Tag-along Stockholder shall have the right to sell in a sale subject to this Section 5.2 the number of shares of Common Stock equal to the product obtained by multiplying (x) the number of shares of Common Stock held by the Tag-along Stockholder by (y) a fraction (A) the numerator of which is equal to the number of shares of Common Stock the Selling Stockholder proposes to sell or transfer to the Proposed Transferee and (B) denominator of which is equal to the number of shares of Common Stock then owned by such Selling Stockholder.

(ii) The Selling Stockholder shall use its commercially reasonable efforts to include in the proposed sale to the Proposed Transferee all of the shares of Common Stock that the Tag-along Stockholders have requested to have included pursuant to the applicable Tag-along Notices, it being understood that the Proposed Transferee shall not be required to purchase shares of Common Stock in excess of the number set forth in the Sale Notice. In the event the Proposed Transferee elects to purchase less than all of the shares of Common Stock sought to be sold by the Tag-along Stockholders, the number of shares to be sold to the Proposed Transferee by the Selling Stockholder and each Tag-along Stockholder shall be reduced so that each such Stockholder is entitled to sell its Pro Rata Portion of the number of shares of Common Stock the Proposed Transferee elects to purchase (which in no event may be less than the number of shares of Common Stock set forth in the Sale Notice).

(iii) Each Tag-along Stockholder who does not deliver a Tag-along Notice in compliance with clause (i) above shall be deemed to have waived all of such Tag-along Stockholder’s rights to participate in such sale, and the Selling Stockholder shall (subject to the rights of any participating Tag-along Stockholder) thereafter be free to sell to the Proposed Transferee its shares of Common Stock at a per share price that is no greater than the per share price set forth in the Sale Notice and on other same terms and conditions which are not materially more favorable to the Selling Stockholder than those set forth in the Sale Notice, without any further obligation to the non-accepting Tag-along Stockholders.

(c) Consideration. Each Tag-along Stockholder participating in a sale pursuant to this Section 5.2 shall receive the same consideration per share after deduction of such Tag-along Stockholder’s proportionate share of the related expenses in accordance with Section 5.2(e).

(d) Conditions of Sale. Each Tag-along Stockholder shall make or provide the same representations, warranties, covenants, indemnities and agreements as the Selling Stockholder makes or provides in connection with the Tag-along Sale (except that in the case of representations, warranties, covenants, indemnities and agreements pertaining specifically to the Selling Stockholder, the Tag-along Stockholder shall make the comparable representations, warranties, covenants, indemnities and agreements pertaining specifically to itself); provided, that all representations, warranties, covenants and indemnities shall be made by the Selling Stockholder and each other Tag-along Stockholder severally and not jointly and any indemnification obligation in respect of breaches of representations and warranties that do not relate to such Tag-along Stockholder shall be in an amount not to exceed the aggregate proceeds received by such Tag-along Stockholder in connection with any sale consummated pursuant to this Section 5.2.

(e) Expenses. The fees and expenses of the Selling Stockholder incurred in connection with a sale under this Section 5.2 and for the benefit of all participating Stockholders (it being understood that costs incurred by or on behalf of the Selling Stockholder for its sole benefit will not be considered to be for the benefit of all participating Stockholders), to the extent not paid or reimbursed by the Company or the Proposed Transferee, shall be shared by all participating Stockholders on a pro rata basis, based on the consideration received by each Stockholder; provided, that no Stockholder shall be obligated to make any out-of-pocket expenditure prior to the consummation of the transaction consummated pursuant to this Section 5.2.

(f) Cooperation. Each Tag-along Stockholder shall take all actions as may be reasonably necessary to consummate the Tag-along Sale, including, without limitation, entering into agreements and delivering certificates and instruments, in each case, consistent with the agreements being entered into and the certificates being delivered by the Selling Stockholder.

(g) Deadline for Completion of Sale. The Selling Stockholder shall have 90 Business Days following the expiration of the Tag-along Period in which to sell the shares of Common Stock described in the Sale Notice, on terms not more favorable to the Selling Stockholder than those set forth in the Sale Notice (which such 90 Business Day period may be extended for a reasonable time not to exceed 120 Business Days to the extent reasonably necessary to obtain any regulatory approvals). If at the end of such period the Selling Stockholder has not completed such sale, the Selling Stockholder may not then effect a sale of Common Stock subject to this Section 5.2 without again fully complying with the provisions of this Section 5.2.

(h) Sales in Violation of the Tag-along Rights. If the Selling Stockholder sells or otherwise transfers to the Proposed Transferee any of its shares of Common Stock in breach of this Section 5.2, then each Tag-along Stockholder shall have the right to sell to the Selling Stockholder, and the Selling Stockholder undertakes to purchase from each Tag-along Stockholder, the number of shares of Common Stock that such Tag-along Stockholder would have had the right to sell to the Proposed Transferee pursuant to this Section 5.2, for a per share amount and form of consideration and upon the terms and conditions on which the Proposed Transferee bought such Common Stock from the Selling Stockholder, but without indemnity being granted by any Tag-along Stockholder to the Selling Stockholder; provided, that nothing contained in this Section 5.2 shall preclude any Tag-along Stockholder from seeking alternative remedies against such Selling Stockholder as a result of its breach of this Section 5.2. The Selling Stockholder shall also reimburse each Tag-along Stockholder for any and all reasonable and documented out-of-pocket fees and expenses, including reasonable legal fees and expenses, incurred pursuant to the exercise or the attempted exercise of the Tag-along Stockholder’s rights under this Section 5.2(h).

5.3 Termination of Certain Covenants. The covenants set forth in Sections 5.1 and 5.2 shall terminate and be of no further force or effect (a) immediately before the consummation of the IPO or (b) when the Company first becomes subject to the periodic reporting requirements of Section 12(g) or 15(d) of the Exchange Act or (c) upon a Sale of the Company, whichever event occurs first.

5.4 Series C Warrants. For the avoidance of doubt, each holder of a Series C Warrant (as defined below) acknowledges and agrees that the Series C Warrants are exercisable only for shares of the Company’s Series C Convertible Preferred Stock (and no other class or series of capital stock of the Company) pursuant to the terms and conditions thereof and shall not be exercisable for shares issued in any Qualified Financing (as defined in the Series C Warrants) other than the Qualified Financing that consisted of the issuance of the Company’s Series C Convertible Preferred Stock. For purposes of this Section 5.4, the “Series C Warrants” shall mean the warrants to purchase securities of the Company issued to various parties together with those certain unsecured convertible promissory notes dated March 1, 2016, April 8, 2016, April 29, 2016 and June 14, 2016.

6. Miscellaneous.

6.1 Successors and Assigns. The rights under this Agreement may be assigned (but only with all related obligations) by a Holder to a transferee of Voting Securities that (a) is an Affiliate of a Holder or (b) is a Holder’s Immediate Family Member or trust for the benefit of an individual Holder or one or more of such Holder’s Immediate Family Members; provided, however, that (i) the Company is, within a reasonable time after such Transfer, furnished with written notice of the name and address of such transferee and the Voting Securities with respect to which such rights are being Transferred and (ii) such transferee agrees in a written instrument delivered to the Company to be bound by and subject to the terms and conditions of this Agreement, including the provisions of Section 2.11. For the purposes of determining the number of shares of Voting Securities held by a transferee, the holdings of a transferee (A) that is an Affiliate or stockholder of a Holder, (B) who is a Holder’s Immediate Family Member or (C) that is a trust for the benefit of an individual Holder or such Holder’s Immediate Family Member shall be aggregated together and with those of the transferring Holder; provided further that all transferees who would not qualify individually for assignment of rights shall have a single attorney-in-fact for the purpose of exercising any rights, receiving notices or taking any action

under this Agreement. The terms and conditions of this Agreement inure to the benefit of and are binding upon the respective successors and permitted assignees of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and permitted assignees any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided herein.

6.3 Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., xxx.xxxxxxxx.xxx) 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.

6.6 Amendments, Terminations and Waivers. Any term of this Agreement may be amended or terminated, and the observance of any term of this Agreement may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written consent of (X) prior to the IPO, (a) the Company and (b) the Holders holding a majority of shares of Series D Convertible Preferred Stock then held by the Holders and (Y) following the IPO (a) the Company and (b) the Holders holding a majority of the Registrable Securities then outstanding, provided that (i) the Company may in its sole discretion waive compliance with Sections 5.1(b) or (c) (and the Company’s failure to object promptly in writing after notification of a proposed Transfer allegedly in violation of Sections 5.1(b) or (c) shall be deemed to be a waiver) and (ii) that any provision hereof may be waived by any waiving party on such party’s own behalf, without the consent of any other party. Notwithstanding the foregoing, this

Agreement may not be amended or terminated and the observance of any term hereof may not be waived with respect to any Stockholder without the written consent of such Stockholder, unless such amendment, termination or waiver applies to all Stockholders in the same fashion. Notwithstanding any other provision of this Agreement, (1) neither Section 4.1(b)(i) nor this subclause (1) shall be amended or waived without the written consent of Xxx Xxxxx so long as Xxx Xxxxx is entitled to designate a director under Section 4.1(b)(i); (2) neither Section 4.1(b)(ii) nor this subclause (2) shall be amended or waived without the written consent of Xxxxx Xxxxx so long as Xxxxx Xxxxx is entitled to designate a director under Section 4.1(b)(ii); (3) neither Section 4.1(b)(iii) nor this subclause (3) shall be amended or waived without the written consent of InterWest Partners LP so long as InterWest Partners LP is entitled to designate a director under Section 4.1(b)(iii); (4) neither Section 4.1(b)(iv) nor this subclause (4) shall be amended or waived without the written consent of NEA so long as NEA is entitled to designate a director under Section 4.1(b)(iv); (5) neither Section 4.1(b)(v) nor this subclause (5) shall be amended or waived without the written consent of Quan and NEA so long as Quan is entitled to designate a director under Section 4.1(b)(v); and (6) neither Section 4.1(b)(vi) nor this subclause (6) shall be amended or waived without the written consent of Xxxxxxx Xxxxxxx so long as Xxxxxxx Xxxxxxx is the CEO Director.

Any amendment, termination or waiver effected in accordance with this Section 6.6 shall be binding on all parties hereto, regardless of whether any such party has consented thereto. No waivers of or exceptions to any term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition or provision.

6.7 Severability. In case any one or more of the provisions contained in this Agreement is for any reason held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement, and such invalid, illegal or unenforceable provision shall be reformed and construed so that it will be valid, legal and enforceable to the maximum extent permitted by law.

6.8 Aggregation of Stock. All shares of Voting Securities held or acquired by Affiliates shall be aggregated together for the purpose of determining the availability of any rights under this Agreement and such Affiliated persons may apportion such rights as among themselves in any manner they deem appropriate.

6.11 Dispute Resolution.

(a) The parties (i) hereby irrevocably and unconditionally submit to the jurisdiction of the state courts of Massachusetts and to the jurisdiction of the United States District Court for the District of Massachusetts and in any Massachusetts State Court sitting in Suffolk County, Commonwealth of Massachusetts for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (ii) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in the United States District Court for the District of Massachusetts and in any Massachusetts State Court sitting in Suffolk County, Commonwealth of Massachusetts and (iii) hereby waive, and agree not to assert, by way of motion, as a defense or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court.

THIS SECTION HAS BEEN FULLY DISCUSSED BY EACH OF THE PARTIES HERETO AND THESE PROVISIONS WILL NOT BE SUBJECT TO ANY EXCEPTIONS. EACH PARTY HERETO HEREBY FURTHER WARRANTS AND REPRESENTS THAT SUCH PARTY HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT SUCH PARTY KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL.

6.12 Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such nonbreaching or nondefaulting party, nor shall it be construed to be a waiver of or acquiescence to any such breach or default, or to any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. All remedies, whether under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

The Company acknowledges that the Stockholders may be in the business of venture capital investing and therefore review the business plans and related proprietary information of many enterprises, including enterprises which may have products or services which compete directly or indirectly with those of the Company.

THIRD AMENDED AND RESTATED STOCKHOLDERS AGREEMENT

THIS AMENDMENT NO. 2 TO THIRD AMENDED AND RESTATED STOCKHOLDERS AGREEMENT (this “Amendment”) is made and entered into as of March 14, 2019, by and among (i) Centrexion Therapeutics Corporation, a Delaware corporation (the “Company”), (ii) the undersigned parties to that certain Third Amended and Restated Stockholders Agreement, dated as of December 18, 2017, as amended by Amendment No. 1 to Third Amended and Restated Stockholders Agreement, dated November 2, 2018 (the “Agreement”) and (iii) the undersigned Additional Stockholders party hereto.

WHEREAS, concurrently with the execution of this Amendment, the Company and the undersigned Additional Stockholders are entering into the Series D Preferred Stock Purchase Agreement, dated as of the date hereof (the “Extension Purchase Agreement”), providing for the sale of shares of Series D Preferred Stock, $0.001 par value per share (the “Series D Preferred Stock”), at the Initial Closing (as defined in the Extension Purchase Agreement) to such Additional Stockholders, and in connection with the Extension Purchase Agreement, the parties hereto desire to provide the Additional Stockholders with certain rights to cause the Company to register shares of Common Stock issuable to the Purchasers, to receive certain information from the Company, to participate in future equity offerings by the Company and to designate the election of a member of the Board, in each case in accordance with the terms of the Agreement, as amended by this Amendment, and to amend the Agreement with respect certain other matters as further set forth in this Amendment;

WHEREAS, pursuant to Section 6.6 of the Agreement, the Agreement may be amended by written agreement of (i) the Company, and (ii) the Holders holding a majority of the shares of Series D Preferred Stock then held by the Holders (collectively, the “Requisite Parties”);

WHEREAS, the Company and the undersigned parties to the Agreement constitute the Requisite Parties; and

WHEREAS, the parties hereto desire to amend the Agreement as set forth herein.

NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto hereby covenant and agree to be bound as follows:

Section 1. Capitalized Terms. Capitalized terms used herein and not otherwise defined herein shall have the respective meanings assigned to them in the Agreement, as amended hereby.

Section 2. Amendments.

(a) Section 4.1(b) of the Agreement is hereby amended and restated in its entirety to read as follows:

“(b) Board Composition. Each Stockholder (with respect to all shares of Voting Securities that such Stockholder owns or over which such Stockholder otherwise exercises voting power) hereby agrees to vote, or cause to be voted, in person, by proxy or by action by written consent, as applicable, from time to time and at all times, in whatever manner as shall be necessary to ensure that at each annual or special meeting of Stockholders at which an election of directors is held or pursuant to any written consent of the Stockholders, the following persons shall be elected to the Board:

(i) For so long as Sol J. Barer holds shares of Common Stock or Preferred Stock, one individual designated by Sol J. Barer, which individual shall initially be Sol J. Barer, Ph.D.;

(ii) For so long as Isaac Blech holds shares of Common Stock or Preferred Stock, one individual designated by Isaac Blech, which individual shall initially be Isaac Blech;

(iii) For so long as InterWest Partners LP (“InterWest”) holds shares of Common Stock or Preferred Stock, one individual designated by InterWest (the “InterWest Designee”), which individual shall initially be Arnold L. Oronsky, Ph.D.;

(vi) For so long as LAV Biosciences Fund V, L.P. (“LAV”) holds shares of Series D Convertible Preferred Stock, one individual designated by LAV (the “LAV Designee”), which individual shall initially be Hongbo Lu, Ph.D.;

(vii) The Company’s Chief Executive Officer (the “CEO Director”), who shall initially be Jeffrey B. Kindler, provided that if for any reason the CEO Director shall cease to serve as the Chief Executive Officer of the Company, each of the Stockholders shall promptly vote their respective shares (i) to remove the former Chief Executive Officer from the Board if such person has not resigned as a member of the Board and (ii) to elect such person’s replacement as Chief Executive Officer of the Company as the new CEO Director;

(viii) The Company’s Chief Scientific Officer (the “CSO Director”), who shall initially be James N. Campbell, M.D., provided that if for any reason the CSO Director shall cease to serve as the Chief Scientific Officer of the Company, each of the Stockholders shall promptly vote their respective shares to remove the former Chief Scientific Officer from the Board if such person has not resigned as a member of the Board; and

(ix) Subject to Sections 4.1(b)(i) through (viii), any individual designated by the Board, three of which individuals shall initially be Daniel N. Mendelson, Joseph R. Swedish and Shawn Tomasello.

To the extent that any of clauses (i) through (viii) above shall not be applicable, any member of the Board who would otherwise have been designated in accordance with the terms thereof shall instead be designated by the Board.”

(b) Section 5.1(e) shall be added to the Agreement to read as follows:

“(e) Each transferee or assignee of any Voting Securities subject to this Agreement shall continue to be subject to the terms of Section 4 hereof, and, as a condition precedent to the Company’s recognition of such transfer, each transferee or assignee shall agree in writing to be subject to each of the terms of this Agreement (including Section 4 hereof) by executing and delivering an Adoption Agreement in form and substance satisfactory to the Company. Upon the execution and delivery of an Adoption Agreement by any transferee, such transferee shall be deemed to be a party hereto as if such transferee were the transferor and such transferee’s signature appeared on the signature pages of this Agreement and shall be deemed to be a Stockholder, or Key Holder and Stockholder, as applicable. The Company shall not permit the transfer of the Voting Securities subject to this Agreement on its books or issue a new certificate representing any such Voting Securities unless and until such transferee shall have complied with the terms of this Subsection 5.1(e). Each certificate instrument, or book entry representing the Voting Securities subject to this Agreement if issued on or after the date of this Agreement shall be notated by the Company with the legend set forth in Subsection 5.1(b).”

“6.6 Amendments, Terminations and Waivers. Any term of this Agreement may be amended or terminated, and the observance of any term of this Agreement may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written consent of (X) prior to the IPO, (a) the Company and (b) the Holders holding a majority of shares of Series D Convertible Preferred Stock then held by the Holders and (Y) following the IPO (a) the Company and (b) the Holders holding a majority of the Registrable Securities then outstanding, provided that (i) the Company may in its sole discretion waive compliance with Sections 5.1(b) or (c) (and the Company’s failure to object promptly in writing after notification of a proposed Transfer allegedly in violation of Sections 5.1(b) or (c) shall be deemed to be a waiver) and (ii) that any provision hereof may be waived by any waiving party on such party’s own behalf, without the consent of any other party. Notwithstanding the foregoing, this Agreement may not be amended or terminated and the observance of any term hereof may not be waived with respect to any Stockholder without the written consent of such Stockholder, unless such amendment, termination or waiver applies to all Stockholders in the same fashion. Notwithstanding any other provision of this Agreement, (1) neither Section 4.1(b)(i) nor this subclause (1) shall be amended or waived without the written consent of Sol Barer so long as Sol Barer is entitled to designate a director under Section 4.1(b)(i); (2) neither Section 4.1(b)(ii) nor this subclause (2) shall be amended or waived without the written consent of Isaac Blech so long as Isaac Blech is entitled to designate a director under Section 4.1(b)(ii); (3) neither Section 4.1(b)(iii) nor this subclause (3) shall be amended or waived without the written consent of InterWest Partners LP so long as InterWest Partners LP is entitled to designate a director under Section 4.1(b)(iii); (4) neither Section 4.1(b)(iv) nor this subclause (4) shall be amended or waived without the written consent of NEA so long as NEA is entitled to designate a director under Section 4.1(b)(iv); (5) neither Section 4.1(b)(v) nor this subclause (5) shall be amended or waived without the written consent of Quan and NEA so long as Quan is entitled to designate a director under Section 4.1(b)(v); (6) neither Section 4.1(b)(vi) nor this subclause (6) shall be amended or waived without the written consent of LAV so long as LAV is entitled to designate a director under Section 4.1(b)(vi); and (7) neither Section 4.1(b)(vii) nor this subclause (7) shall be amended or waived without the written consent of Jeffrey Kindler so long as Jeffrey Kindler is the CEO Director. The Company shall give prompt notice of any amendment or termination hereof or waiver hereunder to any party hereto that did not consent in writing to such amendment, termination or waiver. Any amendment, termination or waiver effected in accordance with this Section 6.6 shall be binding on all parties hereto, regardless of whether any such party has consented thereto. No waivers of or exceptions to any term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition or provision.”

Section 3. Joinder of Additional Stockholders to the Agreement.

(a) As a result of the execution of this Amendment, the undersigned persons listed as Additional Stockholders, if not already a party thereto, are hereby joined to, and bound by the terms and conditions of, the Agreement, as amended hereby, as Stockholders effective as of the date hereof. Execution of this Amendment shall be deemed a counterpart signature page to the Agreement for purposes of Section 6.9 of the Agreement, as amended hereby.

(b) Schedule I to the Agreement shall be replaced with Schedule I attached to this Amendment.

Section 4. No Other Amendments; Conflicts. No term or provision of the Agreement shall be affected by this Amendment, unless specifically set forth herein and any term or provision not affected by this Amendment shall remain in full force and effect following the date hereof. In the event of a conflict between the terms of the Agreement and the terms of this Amendment, the terms of this Amendment shall control.

Section 5. Governing Law. This Amendment and the rights and obligations of the parties hereto shall be governed, construed and interpreted in all respects in accordance with the internal laws of the Commonwealth of Massachusetts without regard to its choice of laws principles.

Section 6. Captions; Pronouns. All articles and section headings or captions contained in this Amendment are inserted only as a matter of convenience and for reference and in no way define, limit, extend or describe the scope of this Amendment or the intent of any provision thereof. References in the Agreement to the Agreement shall mean the Agreement, as amended by this Amendment.

Section 7. Severability. If any provision of this Amendment or application to any party or circumstance shall be determined by any court of competent jurisdiction to be invalid or unenforceable to any extent, the remainder of this Amendment or the application of such provision to any other party or circumstances shall not be affected thereby, and each provision shall be valid and shall be enforced to the fullest extent permitted by law.

Section 8. Counterparts. This Amendment may be executed in multiple counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same instrument. The exchange of copies of this Amendment and of signature pages by facsimile transmission or other electronic means shall constitute effective execution and delivery of this Amendment as to the parties and may be used in lieu of the original Amendment for all purposes.
