WHEREAS, in order to induce the Series C Investors to purchase the Company’s Series C Preferred Stock, the Existing Investors and the Company desire to amend and restate the Prior Agreement, including the rights and obligations set forth therein, in each as set forth herein.

NOW, THEREFORE, the parties hereto hereby agree as follows:

1.2 Request for Registration.

(a) Subject to the conditions of this Section 1.2, if the Company shall receive at any time after the earlier of (i) November 12, 2025 or (ii) six months following the IPO, a written request from the Initiating Holders that the Company file a registration statement under the Securities Act covering the registration of Registrable Securities which would have an aggregate offering price of not less than $15,000,000, then the Company shall within twenty (20) days of the receipt thereof, give written notice of such request to all Holders, and subject to the limitations of this Section 1.2, use commercially reasonable efforts to effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities that the Holders request to be registered in a written request received by the Company within twenty (20) days of the mailing of the Company’s notice pursuant to this Section 1.2(a).

(b) If 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 1.2(a) and the Company shall include such information in the written notice referred to in Section 1.2(a). The underwriter will be selected by the Initiating Holders and shall be reasonably acceptable to the Company. In such event, the right of any Holder to include its 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 enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this Section 1.2, if the underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all Holders of Registrable Securities which would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated, first, to the Initiating Holders and each Investor that participated in the underwriting as a Holder on a pro rata basis based on the total number of Registrable Securities held by the Initiating Holders and participating Investors; and second, to any Holder on a pro rata basis among all such Holders.

(c) Notwithstanding the foregoing, if the Company shall furnish to the Holders requesting a registration statement pursuant to this Section 1.2 a certificate signed by the President of the Company stating that, in the good faith judgment of the Board, it would be detrimental to the Company and its stockholders for such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, the Company shall have the right to defer taking action with respect to such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holders; provided, however, that the Company may not utilize this right more than once in any twelve (12) month period.

(d) In addition, the Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section 1.2:

(i) after the Company has effected two (2) registrations pursuant to this Section 1.2 and such registrations have been declared or ordered effective;

(ii) during the six-month period following the effective date of the registration statement pertaining to an IPO;

(iii) if, within thirty (30) days of a registration request by the Initiating Holders, the Company gives notice to the Holders of its intent to file a registration statement for an IPO within ninety (90) days; or

(iv) 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 1.10 below.

1.3 Company Registration.

(a) If (but without any obligation to do so) the Company proposes to register (including for this purpose a registration effected by the Company for stockholders other than the Holders) any of its stock or other securities under the Securities Act in connection with the public offering of such securities solely for cash (other than a registration relating solely to the sale of securities to participants in a Company stock plan, registration on any form which does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities which are also being registered), the Company shall, at such time, promptly give each Holder written notice of such registration. Upon the written request of each Holder given within twenty (20) days after mailing of such notice by the Company in accordance with Section 5.6, the Company shall, subject to the provisions of Section 1.3(b), cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to be registered. Registrations effected pursuant to this Section 1.3 shall not be counted as demands for registration pursuant to Section 1.2.

(b) If the registration statement under which the Company gives notice under this Section 1.3 is for an underwritten offering, the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to be included in a registration pursuant to this Section 1.3 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 Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of the Agreement, if the underwriter determines in good faith that marketing factors require a limitation of the number of shares to be underwritten, the number of shares that may be included in the underwriting shall be allocated, first, to the Company; second, to the Holders on a pro rata basis based on the total number of Registrable Securities held by the Holders; and third, to any stockholder of the Company (other than a Holder) on a pro rata basis. No such reduction shall reduce the amount of securities of the selling Holders included in the registration below thirty percent (30%) of the total amount of securities included in such registration, unless such offering

is the IPO and such registration does not include shares of any other selling stockholders, in which event any or all of the Registrable Securities of the Holders may be excluded in accordance with the immediately preceding sentence. For any Holder which is a partnership or corporation, the partners, retired partners and shareholders of such Holder, or the estates and lineal descendants of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “Holder,” and any pro rata reduction with respect to such “Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence.

(c) The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 1.3 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration.

1.4 Obligations of the Company.

(a) Whenever required under this Section 1 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible:

(i) Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use reasonable efforts to cause such registration statement to become effective, and, upon the request of the Holders of sixty-five percent (65%) of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to 120 days, if earlier, until the distribution contemplated in the registration statement has been completed.

(ii) 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 provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement.

(iii) Furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them.

(iv) Use 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 Holders; provided, that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process, or subject itself to general taxation, in any such states or jurisdictions.

(v) 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 managing underwriter of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement.

(vi) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act or the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing.

(vii) Cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by the Company are then listed.

(viii) Provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration.

(ix) Reasonably cooperate in all necessary respects with (A) counsel in preparation of the customary legal opinions and (B) accountants in preparation of the customary comfort letters, copies of which shall be provided to each Holder so requesting; provided that the Holders shall not be entitled to rely upon such legal opinions and comfort letters other than in accordance with their own respective terms.

1.5 Furnish Information.

(a) It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 1 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 shall be required to effect the registration of such Holder’s Registrable Securities.

(b) The Company shall have no obligation with respect to any registration requested pursuant to Section 1.2 or Section 1.10 if, due to the operation of Section 1.5(a), the number of shares of the Registrable Securities to be included in the registration does not equal or exceed the number of shares required to originally trigger the Company’s obligation to initiate such registration as specified in Section 1.2(a) or Section 1.10(b), as the case may be.

1.6 Expenses of Registration. All expenses (other than underwriting discounts and commissions, stock transfer taxes and fees of counsel to the selling shareholders) incurred in connection with registrations, filings or qualifications pursuant to Section 1.2, Section 1.3 and Section 1.10, including (without limitation) all registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company and the reasonable fees and disbursements of one counsel for the selling Holders (not to exceed $35,000), shall be borne by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 1.2(a) or Section 1.10 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all participating Holders shall bear such expenses pro rata based upon the number of Registrable Securities that were to be registered in

the withdrawn registration); provided, however, that if at the time of such withdrawal, the Holders (i) have learned of a material adverse change in the condition, business, or prospects of the Company that was not known at the time of their request or could have not been reasonably known given the prior communication or information provided by the Company to the Holders and (ii) have withdrawn the request with reasonable promptness following disclosure by the Company of such material adverse change, then the Holders shall not be required to pay any of such expenses.

1.7 Delay of Registration. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 1.

1.8 Indemnification. In the event any Registrable Securities are included in a registration statement under this Section 1:

(a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law; and the Company will pay to each such Holder, underwriter or controlling person any legal or other expenses reasonably incurred, as incurred, by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 1.8(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld, conditioned or delayed), nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for inclusion in a registration statement in connection with such registration by any such Holder, underwriter or controlling person and; provided further, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Holder or underwriter, or any person controlling such Holder or underwriter, from whom the person asserting any such losses, claims, damages or liabilities purchased shares in the offering, if a copy of the prospectus (as then amended or supplemented) was not sent or given by or on behalf of such Holder or underwriter to such person, if required by law so to have been delivered by such Holder, at or prior to the written confirmation of the sale of the shares to such person, and if the prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability.

(b) To the extent permitted by law, each selling Holder, severally and not jointly, will indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the Securities Act, legal counsel and accountants for the Company, any underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter or other Holder, against any losses, claims, damages or liabilities (joint or several) to which any of the foregoing persons may become subject, under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will pay any legal or other expenses reasonably incurred, as incurred, by any person intended to be indemnified pursuant to this Section 1.8(b), in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 1.8(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld, conditioned or delayed, provided that in no event shall any indemnity under this Section 1.8(b) plus any contribution under this Section 1.8 exceed the net proceeds from the offering received by such Holder.

(c) Promptly after receipt by an indemnified party under this Section 1.8 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.8, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties which 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 proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 1.8, but the omission to so deliver written 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 1.8.

(d) If the indemnification provided for in this Section 1.8 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense 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 in connection with the statements or omissions that

resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations; provided, that, in no event shall any contribution under this Section 1.8(d) when combined with any payment made pursuant to Section 1.8(b) hereunder by a Holder exceed the net proceeds from the offering received by such Holder. 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 alleged untrue statement of a material fact or the omission to state 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.

(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 1.8 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 1 and otherwise shall survive the termination of this Agreement.

1.9 Reports Under Exchange Act. With a view to making available to the Holders the benefits of Rule 144 promulgated under the Act, (“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 agrees to:

(a) make and keep public information available, as those terms are understood and defined in SEC Rule 144, at all times after ninety (90) days after the effective date of the IPO;

(b) 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) 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 first registration statement filed by the Company), the Securities Act and the Exchange Act (at any time after it 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 it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form.

1.10 Form S-3 Registration. In case the Company shall receive from the Initiating Holders, a written request or requests that the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Initiating Holder or Holders, the Company will:

(a) promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and

(b) use reasonable efforts to effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Initiating Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance, pursuant to this Section 1.10: (i) if Form S-3 is not available for such offering by the Initiating Holders; (ii) if the Initiating Holders propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public (net of any underwriters’ discounts or commissions) of less than $2,500,000; (iii) after the Company has effected two (2) registrations pursuant to this Section 1.10 in a twelve (12) month period and such registrations have been declared or ordered effective; (iv) if the Company shall furnish to the Initiating Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board, it would be detrimental to the Company and its stockholders for such Form S-3 registration to be filed at such time, in which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than ninety (90) days after receipt of the request of the Holder or Holders under this Section 1.10; provided, however, that the Company shall not utilize this right more than once in any twelve (12) month period; or (v) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance or otherwise subject itself to general taxation. Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request or requests of the Holders. Registrations effected pursuant to this Section 1.10 shall not be counted as demands for registration effected pursuant to Section 1.2.

1.11 Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Section 1 may be assigned (but only with all related obligations) by (i) a Holder that is a partnership, to any subsidiary, parent, partner, retired partner or affiliated fund of such Holder, (ii) a Holder that is a limited liability company, to any member or former member of such Holder, (iii) a Holder who is an individual, to such Holder’s family member or trust for the benefit of such Holder or such Holder’s family member, (iv) a Major Investor to an Affiliate; or (v) a Holder to any other person acquiring at least 500,000 Registrable Securities (as appropriately adjusted for any stock split, dividend, combination or other recapitalization or like transactions) (or all of such transferring Holder’s shares if less); provided (in all cases) (a) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; (b) such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this Agreement, including without limitation the provisions of Section 2 below; and (c) such assignment shall be effective only if immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Securities Act.

1.12 Termination of Registration Rights. No Holder shall be entitled to exercise any right provided for in this Section 1 after the earlier to occur of the following: (i) the fifth anniversary of the effective date of the IPO, (ii) the date when all Registrable Securities held by such Holder can be sold in any ninety (90) day period without registration in compliance with Rule 144 or (iii) upon an Acquisition of the Company by a company subject to and in compliance with the reporting provisions of the Exchange Act, as amended.

1.13 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of the Holders of at least 65% of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective holder of any securities of the Company which would allow such holder or prospective holder to include such securities in any registration filed under Section 1.2 hereof, 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 his securities will not reduce the amount of the Registrable Securities of the Holders which is included.

2. Market Stand-Off Agreement. Each Holder hereby agrees that in connection with an IPO, upon request of the underwriters managing such IPO, that such Holder shall not sell, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Common Stock (or other securities) of the Company held by such Holder immediately before the effective date of the registration statement for the IPO (other than those included in the registration), for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the effective date of the registration statement for the IPO; provided, however, that all executive officers, directors and holders of one percent (1%) or more of the outstanding capital stock of the Company are subject to similar restrictions. Any release from the lock up restrictions, any time during the market stand-off period, shall be done pro rata among the Holders of Registrable Securities, so that each Holder of Registrable Securities may sell, transfer or otherwise dispose of an equal percentage of his, her or its shares originally subject to the lock-up restrictions. Each Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 2 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Notwithstanding the foregoing, (i) any Holder that is an entity shall be permitted to distribute securities of the Company during the market stand-off period to its stockholders, members, former members, partners, former partners or other equity holders, or to an entity controlling, controlled by or under common control with such Investor, so long as each distributee agrees in writing to be bound by the restrictions set forth herein and (ii) the lock-up restrictions shall not apply to transactions or announcements, in each case, relating to securities acquired in the IPO or securities acquired in open market or other transactions from and after the IPO or that otherwise do not involve or relate to shares of capital stock of the Company owned by a Holder prior to the IPO.

3. Covenants of the Company.

3.2 Matters Requiring Investor Director Approval. So long as any holders of Preferred Stock are entitled to elect one or more Preferred Directors (as defined in the Restated Certificate), the Company hereby covenants and agrees with the Investors that the Company shall not, and shall not permit any of its subsidiaries to, without the affirmative vote or consent of the Board, including the Preferred Director Approval:

3.3 Inspection. The Company shall permit each Significant Investor, at such Significant Investor’s expense, to visit and inspect the Company’s properties, to examine its books of account and records and to discuss the Company’s affairs (including any written correspondence with the U.S. Food and Drug Administration or any comparable regulatory agency outside of the United States), finances and accounts with its officers, all at such reasonable times as may be convenient to the Company and such Significant Investor; provided, however, that the Company shall not be obligated pursuant to this Section 3.3 to provide access to any information which it reasonably considers to be a trade secret or similar confidential information.

3.4 Right of First Offer.

(a) Subject to the terms and conditions specified in this Section 3.4, the Company hereby grants to each Major Investor the right of first offer with respect to future sales by the Company of its Shares (as hereinafter defined). A Major Investor shall be entitled to apportion the right of first offer hereby granted it among itself and its partners and Affiliates in such proportions as it deems appropriate. Each time following the date hereof that the Company proposes to offer any shares of, or securities convertible into or exchangeable or exercisable for any shares of, any class of its capital stock (“Shares”), the Company shall first make an offering of such Shares to each Major Investor in accordance with the following provisions. The Company shall deliver a notice in accordance with Section 5.6 to the Major Investors stating (i) its bona fide intention to offer such Shares, (ii) the number of such Shares to be offered, and (iii) the price and terms upon which it proposes to offer such Shares. If any prospective purchaser has offered to pay for any Shares with property, services or any other non-cash consideration, then the Major Investors shall nevertheless have the right to pay for such Shares with cash in an amount equal to the fair market value of the non-cash consideration offered by the prospective purchaser, where the fair market value of such non-cash consideration shall be conclusively determined in good faith by the Board.

(b) By written notification received by the Company, within twenty (20) calendar days after delivery of the notice, the Major Investor may elect to purchase or obtain, at the price and on the terms specified in the notice, up to that portion of such Shares that equals the proportion that the number of shares of Common Stock issued and held, or issuable upon conversion of the Preferred Stock then held, by such Major Investor bears to the total number of shares of Common Stock of the Company then outstanding (assuming full conversion of all outstanding convertible securities). The Company shall promptly, in writing, inform each Major Investor that elects to purchase all the shares available to it (a “Fully-Exercising Investor”) of any other Major Investor’s failure to do likewise. During the ten (10) day period commencing after such information is given, each Fully-Exercising Investor may elect to purchase that portion of the Shares for which Major Investors were entitled to subscribe but which were not subscribed for that is equal to the proportion that the number of shares of Common Stock issued and held, or issuable upon conversion of Preferred Stock then held, by such Fully-Exercising Investor bears to the total number of shares of Common Stock issued and held, or issuable upon conversion of the Preferred Stock then held, by all Fully-Exercising Investors who wish to purchase some of the unsubscribed shares.

(c) If all Shares that Major Investors are entitled to obtain pursuant to Section 3.4(b) are not elected to be obtained as provided in Section 3.4(b) hereof, the Company may, during the ninety (90) day period following the expiration of the period provided in Section 3.4(b) hereof, offer the remaining unsubscribed portion of such Shares to any person or persons at

a price not less than, and upon terms no more favorable to the offeree than those specified in the notice. If the Company does not enter into a definitive binding agreement for the sale of the Shares within such period, or if such agreement is not consummated within sixty (60) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such Shares shall not be offered unless first reoffered to the Major Investors in accordance herewith.

(d) The right of first offer in this Section 3.4 shall not be applicable to the Exempted Securities (as defined in the Restated Certificate) or sales of Series C Preferred Stock pursuant to the Purchase Agreement.

(e) Notwithstanding the foregoing, the right of first offer in this Section 3.4 shall not be applicable to with respect to any Major Investor and any subsequent issuance of securities if, (i) at the time of such subsequent issuance of securities, such Major Investor is not an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities Act, and (ii) such subsequent issuance of securities is otherwise being offered only to accredited investors as defined in Rule 501(a) of Regulation D promulgated under the Securities Act.

3.5 Confidential Information and Invention Assignment and Non-Solicitation Agreements. The Company shall cause each employee and consultant/independent contractor now or hereafter employed or engaged by the Company or any of its subsidiaries (including, without limitation, Xxxx X. Xxxxxxxx, Xx.) to execute and deliver a confidential information and invention assignment agreement substantially in a form approved by counsel to the Investors and the Board, provided, that such form of confidential information and invention assignment agreement shall include non-solicitation provisions (to apply during the term of employment/engagement and for at least 6 months thereafter) and non-compete provisions (to apply during the term of employment/engagement) customary in substance and form. In addition, the Company shall not amend, modify, terminate, waive, or otherwise alter, in whole or in part, any such confidential information and invention assignment agreement without the consent of the Board, including the Preferred Director Approval.

3.6 Indemnification. The Company shall use commercially reasonable efforts to provide that its Restated Certificate and Bylaws provide for indemnification of officers and directors of the Company to the maximum extent permitted by law. The Company hereby acknowledges that one or more of the directors nominated to serve on the Board by the Investors (each an “Investor Director”) may have certain rights to indemnification, advancement of expenses and/or insurance provided by one or more of the Investors and certain of their Affiliates (collectively, the “Investor Indemnitors”). The Company hereby agrees (a) that it is the indemnitor of first resort (i.e., its obligations to any such Investor Director are primary and any obligation of the Investor Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by such Investor Director are secondary), (b) that it shall be required to advance the full amount of expenses incurred by such Investor Director and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement by or on behalf of any such Investor Director to the extent legally permitted and as required by the Restated Certificate or the Bylaws of the Company (or any agreement between the Company and such Investor Director), without regard to any rights such Investor Director may have against the Investor Indemnitors, and, (c) that it irrevocably waives, relinquishes and releases the Investor Indemnitors from any and all claims against the Investor Indemnitors for contribution,

subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Investor Indemnitors on behalf of any such Investor Director with respect to any claim for which such Investor Director has sought indemnification from the Company shall affect the foregoing and the Investor Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of such Investor Director against the Company. The Investor Directors and the Investor Indemnitors are intended third-party beneficiaries of this Section 3.6 and shall have the right, power and authority to enforce the provisions of this Section 3.6 as though they were a party to this Agreement.

3.7 Directors’ & Officers’ Liability. The Company shall obtain, from financially sound and reputable insurers, and thereafter maintain a policy or policies of directors’ and officers’ liability insurance in an amount of coverage not less than $5,000,000 (“D&O Insurance”) on terms and conditions satisfactory to the Board, including the Preferred Director Approval, and shall cause such policy to be maintained until such time as the Board, including the approval of each Preferred Director, determines that such insurance should be discontinued.

3.8 Key-Man Life Insurance. The Company shall use its reasonable efforts to obtain, from financially sound and reputable insurers, term “key-person” insurance on Xxxx X. Xxxxxxxx, Xx. (the “Founder”) and maintain such insurance for so long as the Founder is the Chief Executive Officer of the Company, in an amount of at least $1,000,000 and on terms and conditions satisfactory to the Board, and will use commercially reasonable efforts to cause such policy to be maintained until such time as the Board, including the Preferred Director Approval, determines that such insurance should be discontinued. Such key-person policy shall name the Company as loss payee.

3.9 Board Matters. The Board shall convene for meetings at least six times per year (in person or by teleconference or videoconference) unless otherwise approved by the Board, including the Preferred Director Approval. No Board meeting shall be held unless a majority of the then-serving directors are present in person or in attendance by electronic means, including a majority of the then-serving Preferred Directors, if any. Upon request, the Company shall promptly reimburse in full, each non-employee director of the Company for his or her reasonable and documented out-of-pocket expenses incurred (a) in the course of pre-approved business conducted on behalf of the Company or (b) in connection with attending meetings of the Board or any committee thereof, including, without limitation, reasonable travel expenses.

3.10 Board Committees. If the Board establishes any committee thereof, each Preferred Director shall have the right, but not the obligation, to serve as a member of any such committee and to serve as a member of the board of directors or similar governing body of any subsidiary of the Company. Each Preferred Director shall have the right, but not the obligation, to attend as an observer all meetings of scientific and other advisory boards.

3.11 Stock Vesting. Unless otherwise approved by the Board, including the Preferred Director Approval, all stock, stock options and other stock equivalents issued after the date of this Agreement to employees, directors, consultants and other service providers shall be subject to vesting no earlier than as follows: (a) twenty-five percent (25%) of such stock shall vest at the end of the first year following the earlier of the date of issuance or such person’s services

commencement date with the Company, and (b) seventy-five percent (75%) of such stock shall vest in equal monthly installments over the remaining three (3) years. With respect to any shares of stock purchased by any such person still subject to vesting, the Company’s repurchase option shall provide that upon such person’s termination of employment or service with the Company, with or without cause, the Company or its assignee shall have the option to purchase at no more than cost any unvested shares of stock held by such person. Without the prior approval by the Board, including the Preferred Director Approval, the Company shall not amend, modify, terminate, waive or otherwise alter, in whole or in part, any stock purchase, stock restriction or option agreement with any existing employee or service provider if such amendment would cause it to be inconsistent with this Section 3.11. In addition, unless otherwise approved by the Board, including the Preferred Director Approval, the Company shall not offer or allow any acceleration of vesting (other than, for the avoidance of doubt, pursuant to the terms of agreements in effect as of the date of this Agreement). No stock option, restricted stock and similar equity grant issued to officers and consultants shall be transferable until such time as such stock option, restricted stock and similar equity grant is fully vested. No stock option shall have a maximum term of more than ten (10) years.

committee and (b) 24 hours prior to the time of such proposed Board or committee meeting; provided, that such Observer agrees to hold in confidence in accordance with Section 3.13 all information regarding the Company provided to such Observer acting in such capacity; and provided, further, that such Observer may be excluded from any meeting or portion thereof and the Company reserves the right to withhold any information from such Observer if the Company reasonably determined in good faith that such withholding of information or exclusion is reasonably necessary to preserve the attorney-client privilege, to protect highly confidential proprietary information, if the Board determines in good faith that there exists, with respect to the subject of such deliberation or of such Board materials, an actual or reasonably likely conflict of interest between such Observer and the Company.

3.13 Confidentiality. Each Investor agrees, severally and not jointly, to use the same degree of care as such Investor uses to protect its own confidential information for any information obtained pursuant to Section 3.1, Section 3.3 and Section 3.12 hereof which the Company identifies in writing as being proprietary or confidential and such Investor acknowledges that it will not, unless otherwise required by law, regulation, rule, court order or subpoena or the rules of any national securities exchange, association or marketplace, disclose such information without the prior written consent of the Company except such information that (a) was in the public domain prior to the time it was furnished to such Investor, (b) is or becomes (other than as a result of a breach of this Section 3.13 by such Investor) generally available to the public, (c) was in such Investor’s possession or known by such Investor prior to receipt from the Company, (d) is or has been made known or disclosed to such Investor by a third party without a breach of any obligation of confidentiality such third party may have to the Company, or (e) was independently developed or conceived by such Investor without any use of the Company’s confidential information.

Xxxx or Farallon or any representative or Observer of Surveyor, X. Xxxx or Farallon. In addition, the Company acknowledges and agrees that in no event shall Surveyor’s, X. Xxxx’x or Farallon’s confidentiality and non-use obligations hereunder in any manner be deemed or construed as limiting Surveyor or its representatives’ (or any of their respective Affiliates), X. Xxxx or its representatives’ (or any of their respective Affiliates’) or Farallon’s or its representatives’ (or any of their respective Affiliates’) ability to trade any security of a Public Company.

3.14 Brokers or Finders.

4. Restrictions on Transferability of Securities; Compliance with Securities Act.

4.1 Restrictions on Transferability. The Preferred Stock and the Registrable Securities shall not be sold, pledged, or otherwise transferred, and the Company shall not recognize and shall issue stop-transfer instructions to its transfer agent with respect to any such sale, pledge, or 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 purchaser, pledgee, or transferee of the Preferred Stock and the Registrable Securities held by such holder to agree to take and hold such securities subject to the provisions and upon the conditions specified in this Agreement.

4.2 Notice of Proposed Transfers. The holder of each certificate representing Restricted Securities by acceptance thereof agrees to comply in all respects with the provisions of this Section 4.2.

(a) Before any proposed sale, pledge, or transfer of any Restricted 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 sale, pledge, or transfer. Each such notice shall describe the manner and circumstances of the proposed sale, pledge, or 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 sale, pledge, or transfer of such Restricted 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 sale, pledge, or transfer of the Restricted Securities may be effected without registration under the Securities Act, whereupon the holder of such Restricted Securities shall be entitled to sell, pledge, or transfer such Restricted Securities in accordance with the terms of the notice given by the holder to the Company. Each certificate or instrument evidencing the Restricted 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 3.6 of the Purchase Agreement, except that such certificate shall not bear such restrictive legend if, in the opinion of counsel for such holder and the Company, such legend is not required in order to establish compliance with any provisions of the Securities Act.

(b) Notwithstanding the provisions of subsection (a) above, no such restriction shall apply to a transfer by a holder that is (i) a partnership transferring to its partners or former partners in accordance with partnership interests, (ii) a corporation transferring to a wholly-owned subsidiary, Affiliate or a parent corporation that owns all of the capital stock of the holder, (iii) a limited liability company transferring to its members or former members in accordance with their interest in the limited liability company, (iv) an entity transferring to an Affiliate, or (v) an individual transferring to the holder’s family member or trust for the benefit of an individual holder; provided that in each case the transferee will agree in writing to be subject to the terms of this Agreement to the same extent as if he were an original Holder hereunder.

All notices and other communications to the Investors shall be made to their respective e-mail addresses or addresses set forth in Schedule A attached hereto. Notwithstanding the foregoing, the Company and any Investor may modify its e-mail address or address for notices hereunder by providing at least ten (10) calendar days advance written notice of such modification to the other parties in accordance with this Section 5.6.

(b) Consent to Electronic Notice. Each Investor consents to the delivery of any stockholder notice pursuant to the Delaware General Corporation Law (the “DGCL”), as amended or superseded from time to time, by electronic transmission pursuant to Section 232 of the DGCL (or any successor thereto) at the electronic mail address set forth below such Investor’s name in Schedule A attached hereto, as updated from time to time in accordance with Section 5.6(a), or as on the books of the Company. To the extent that any notice given by means of electronic transmission is returned or undeliverable for any reason, the foregoing consent shall be deemed to have been revoked until a new or corrected electronic mail address has been provided, and such attempted electronic notice shall be ineffective and deemed to not have been given. Each Investor agrees to promptly notify the Company of any change in such Investor’s electronic mail address, and that failure to do so shall not affect the foregoing.

5.7 Amendments and Waivers. Any term of this Agreement may be amended 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 the Company and the Holders of at least 65% of the Registrable Securities then outstanding; provided, however, that if any amendment or waiver operates in a manner that materially and disproportionately discriminates against a Holder in relation to the other Holders, the consent of such Holder shall also be required for such amendment or waiver; provided, further, however, that the addition of new parties to this Agreement or the proportionate adjustment in rights that would result from adding new parties shall not be deemed to be amendments which materially and disproportionately discriminate against such Major Investor; provided, further, that (a) any amendment to Section 1.1(x), 3.1 or 3.3, or any other provision of this Agreement to the extent such provision pertains to Section 1.1(x), 3.1 or 3.3, requires the consent of the holders of at least 65% of the Registrable Securities then outstanding and held by the Significant Investors, and (b) any amendment to Section 1.1(k), 3.4 or 3.20, or any other provision of this Agreement to the extent such provision pertains to Section 1.1(k), 3.4 or 3.20, requires the consent of the holders of at least 65% of the Registrable Securities then outstanding and held by the Major Investors; provided, further, that if Section 3.4 is waived with respect to a particular issuance of Shares, and a Major Investor nevertheless participates in such issuance by separate agreement with the Company (such Major Investor, a “Participating Investor”), then such waiver of Section 3.4 shall only be effective if each other Major Investor is provided the opportunity to purchase a proportional number of the Shares offered by the Company in such issuance (based on the pro rata purchase right of such Major Investor set forth in Section 3.4, assuming a transaction size determined based upon the amount purchased by the Participating Investor that invested the largest percentage in such issuance relative to the amount such Participating Investor would have been entitled to purchase pursuant to the calculation of the pro rata right in Section 3.4 had such provision not been waived). Any amendment effected in accordance with this Section shall be binding upon each Investor and the Company; provided, however, that no consent or approval of any Investor shall be required to add persons as parties to this Agreement as Investors or to revise Schedule A to include such parties. Any amendment effected in accordance with this Section shall be binding upon each Holder of Registrable Securities and the Company.

5.8 Severability. If any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect, such provision will be enforced to the maximum extent possible and such invalidity, illegality or unenforceability will not affect any other provision of this Agreement. In such event, the parties shall negotiate, in good faith, a legal, valid and enforceable substitute provision which most nearly effects the intent of the parties in entering into this Agreement.

5.9 Additional Parties. Persons who become “Purchasers” after the effective date of this Agreement pursuant to and in accordance with the Purchase Agreement (each, an “Additional Party”), upon execution and delivery of counterpart signature pages to this Agreement, shall become parties hereto, each such Additional Party thereby agreeing to be bound by and subject to the terms of this Agreement as an Investor hereunder. Each such Additional Party shall thereafter shall be deemed an Investor for all purposes under this Agreement.

5.10 Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any party to this Agreement, upon any breach or default of any other party to this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in 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. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

5.11 Aggregation of Stock. All shares of Registrable 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.

5.12 Advice of Counsel. EACH PARTY TO THIS AGREEMENT ACKNOWLEDGES THAT, IN EXECUTING THIS AGREEMENT, SUCH PARTY HAS HAD THE OPPORTUNITY TO SEEK THE ADVICE OF INDEPENDENT LEGAL COUNSEL, AND HAS READ AND UNDERSTOOD ALL OF THE TERMS AND PROVISIONS OF THIS AGREEMENT. THIS AGREEMENT SHALL NOT BE CONSTRUED AGAINST ANY PARTY BY REASON OF THE DRAFTING OR PREPARATION HEREOF.

5.13 Entire Agreement. This Agreement (including any Schedules hereto) constitutes the full and entire understanding and agreement among the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled. Upon the effectiveness of this Agreement, the Prior Agreement shall be deemed amended and restated and superseded and replaced in its entirety by this Agreement, and shall be of no further force or effect.
