3.3 Underwriting Requirements.

3.3.1 Inclusion. If, pursuant to Section 3.1, 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 3.1, and the Company shall include such information in the Demand Notice. The underwriter(s) will be selected by the Company, subject only to the reasonable approval of the holders of a majority of Registrable Securities held by 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. All Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in Section 3.4(e)) enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting. Notwithstanding any other provision of this Section 3.3, if the managing 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 or held 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 owned or 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.

3.3.2 Underwriter Cutback. In connection with any offering involving an underwriting of shares of the Company’s capital stock pursuant to Section 3.2, 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. 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 or held 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 (a) 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, (b) the number of Registrable Securities included in the offering be reduced below 30% 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 or (c) notwithstanding clause (b) above, any Registrable Securities which are not Key Holder Registrable Securities be excluded from such underwriting unless all Key Holder Registrable Securities are first excluded from such offering For purposes of the provision in this Section 3.3.2 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 or held by all Persons included in such “selling Holder,” as defined in this sentence.

3.3.3 Registration Not Effected. For purposes of Section 3.1, a registration shall not be counted as “effected” if, as a result of an exercise of the underwriter’s cutback provisions in Section 3.3.1, 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.

(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 or Free-Writing Prospectus forming a part of such registration statement has been filed;

(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 or Free-Writing Prospectus;

(l) use its commercially reasonable efforts to obtain for the underwriters on the date such securities are delivered to the underwriters for sale pursuant to such registration a legal opinion of the Company’s outside counsel with respect to the registration statement, each amendment and supplement thereto, the prospectus included therein (including the preliminary prospectus) and such other documents relating thereto in customary form and covering such matters of the type customarily covered by legal opinions of such nature;

(m) to the extent the Company is a well-known seasoned issuer (as defined in SEC Rule 405 at the time any request for registration is submitted to the Company in accordance with Section 3.1, if so requested, file an Automatic Shelf Registration Statement to effect such registration; and

(n) if at any time when the Company is required to re-evaluate its well-known seasoned issuer status for purposes of an outstanding Automatic Shelf Registration Statement used to effect a request for registration in accordance with Section 3.1.2 the Company determines that it is not a well-known seasoned issuer and (i) the registration statement is required to be kept effective in accordance with this Agreement and (ii) the registration rights of the applicable Holders have not terminated, use commercially reasonable efforts to promptly amend the registration statement on a form the Company is then eligible to use or file a new registration statement on such form, and keep such registration statement effective in accordance with the requirements otherwise applicable under this Agreement.

3.5 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 3 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.

3.6 Expenses of Registration. All expenses (other than Selling Expenses) incurred in connection with registrations, filings, or qualifications pursuant to Section 3, including 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 Selling Holder Counsel, not to exceed $50,000, shall be borne and paid 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 3.1 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 selling Holders shall bear such expenses pro rata based upon the number of Registrable Securities that were to be included in the withdrawn registration), unless (i) the Holders of a majority of the Registrable Securities agree to forfeit their right to one registration pursuant to Section 3.1.1 or Section 3.1.2, as the case may be, or (ii) if, at the time of such withdrawal, the Holders shall have learned of a material adverse change in the condition, business, or prospects of the Company not known to the Holders at the time of their request and have withdrawn the request with reasonable promptness after learning of such information, then the Holders shall not be required to pay any of such expenses and shall not forfeit their right to one registration pursuant to Section 3.1.1 or Section 3.1.2. All Selling Expenses relating to Registrable Securities registered pursuant to this Section 3 shall be borne and paid by the Holders pro rata on the basis of the number of Registrable Securities registered on their behalf.

3.7 Delay of Registration. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any registration pursuant to this Agreement as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 3.

3.8 Indemnification. If any Registrable Securities are included in a registration statement under this Section 3:

3.8.1 Company Indemnification. To the extent permitted by law, the Company will indemnify and hold harmless each selling Holder, and the partners, members, officers, directors, and stockholders of each such Holder; legal counsel and accountants for each such Holder; any underwriter (as defined in the Securities Act) for each 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 Damages, and the Company will pay to each such Holder, underwriter, controlling Person, or other aforementioned Person any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 3.8.1 shall not apply to amounts paid in settlement of any such claim or proceeding 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 for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any such Holder, underwriter, controlling Person, or other aforementioned Person expressly for use in connection with such registration.

3.8.2 Selling Holder Indemnification. To the extent permitted by law, each selling Holder, severally and not jointly, will indemnify and hold harmless the Company, and 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 (as defined in the Securities Act), any other Holder selling securities in such registration statement, and any controlling Person of any such underwriter or other Holder, against any Damages, in each case only to the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of such selling Holder expressly for use in connection with such registration; and each such selling Holder will pay to the Company and each other aforementioned Person any legal or other expenses reasonably incurred

thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that (a) the indemnity agreement contained in this Section 3.8.2 shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld, conditioned or delayed, and (b) that in no event shall the aggregate amounts payable by any Holder by way of indemnity or contribution under Sections 3.8.2 and 3.8.4 exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of fraud or willful misconduct by such Holder.

3.8.3 Procedures. Promptly after receipt by an indemnified party under this Section 3.8 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 3.8, 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 3.8, solely to the extent that such failure prejudices the indemnifying party’s ability to defend such action.

3.8.4 Contribution. To provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (a) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Section 3.8 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 3.8 provides for indemnification in such case, or (b) contribution under the Securities Act may be required on the part of any party hereto for which indemnification is provided under this Section 3.8, 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:

(i) 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

(ii) in no event shall a Holder’s liability pursuant to this Section 3.8.4, when combined with the amounts paid or payable by such Holder pursuant to Section 3.8.2, exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of fraud or willful misconduct by such Holder.

3.8.5 Underwriting Agreement Controls. 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.

3.8.6 Survival. 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 3.8 shall survive the completion of any offering of Registrable Securities in a registration under this Section 3, and otherwise shall survive the termination of this Agreement.

3.9 Reports under the 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).

3.10 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 a majority of the Registrable Securities then outstanding (the “Requisite Preferred Majority”), enter into any agreement with any holder or prospective holder of any securities of the Company that would provide to such holder or prospective holder the right to include securities in any registration on other than a subordinate basis after all Investors have had the opportunity to include in the registration and offering all shares of Registrable Securities that they wish to so include.

3.11 “Market Stand-off” Agreement. Each Holder hereby agrees that, during the Standoff Period, such Holder will not, without the prior written consent of the Company or the managing underwriter,

(a) lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right, or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock, or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Stock, held immediately before the effective date of the registration statement for such offering; or

(b) 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 (a) or (b) above is to be settled by delivery of Common Stock or other securities, in cash, or otherwise.

The foregoing provisions of this Section 3.11: (w) shall apply only to an IPO (but, for the avoidance of doubt, shall not apply to shares acquired by the Holder in the IPO or in open market transactions after the completion of the IPO); (x) shall not apply, in the case of a Holder that is an entity, to the transfer of any shares during the Standoff Period to an Affiliate of such Holder or any of the Holder’s stockholders, members, partners or other equity holders, provided that such Affiliate, stockholder, member, partner or other equity holder agrees to be bound in writing by the restrictions set forth herein; (y) shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, and (z) shall be applicable to the Holders only if all officers, directors, and stockholders individually owning more than one percent (1%) of the Company’s outstanding Common Stock (after giving effect to conversion into Common Stock of all outstanding Preferred Stock) are similarly bound. Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply pro rata to all directors, officers, and Holders owning more than one percent (1%) of the Company’s outstanding Common Stock (after giving effect to conversion into Common Stock of all outstanding Preferred Stock) subject to such agreements, based on the number of shares subject to such agreements, except that, notwithstanding the foregoing, the Company and the underwriters may, in their sole discretion, waive or terminate these restrictions with respect to up to one percent (1%) of the Company’s then outstanding shares of the Common Stock. For purposes of this Section 3.11, the term “Company” shall include any wholly-owned subsidiary of the Company into which the Company merges or consolidates. In order to enforce the foregoing

covenant, the Company shall have the right to place restrictive legends on the certificates representing the shares subject to this Section 3.11 and to impose stop transfer instructions with respect to such shares until the end of such period. The underwriters in connection with such registration are intended third-party beneficiaries of this Section 3.11 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 3.11 or that are necessary to give further effect thereto.

3.12 Restrictions on Transfer.

3.12.1 Agreement Binding. 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.

3.12.2 Legends. Each certificate or instrument representing (a) the Preferred Stock, (b) the Registrable Securities, and (c) any other securities issued in respect of the securities referenced in clauses (a) and (b), upon any stock split, stock dividend, recapitalization, merger, consolidation, or similar event, shall (unless otherwise permitted by the provisions of Section 3.12.3) be stamped or otherwise imprinted with a legend substantially in the following form:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, 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 Restricted Securities in order to implement the restrictions on transfer set forth in this Section 3.12.

3.12.3 Procedure. The holder of each certificate representing Restricted Securities, by acceptance thereof, agrees to comply in all respects with the provisions of this Section 3. 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 (a) 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; (b) 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 (c) 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. The Company will not require such a legal opinion or “no action” letter (i) in any transaction in compliance with SEC Rule 144 or (ii) in any transaction in which such Holder distributes Restricted 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 3.12. 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 3.12.2, 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. Until the IPO, no Holder shall transfer any Restricted Securities to any person or entity that is determined to be a competitor of the Company, in the good faith judgment of the Board; provided, however that none of the Fund Investors, or any of their respective Affiliates, or AstraZeneca or any of its Affiliates, shall in any circumstances be considered a “competitor” for purposes of this provision.

4. RIGHTS TO FUTURE STOCK ISSUANCES. Subject to the terms and conditions of this Section 4 and applicable securities laws, if the Company proposes to sell any New Securities, the Company shall offer to sell a portion of New Securities to each Major Investor as described in this Section 4. A Major Investor shall be entitled to apportion the right of first refusal hereby granted to it among itself and its Affiliates in such proportions as it deems appropriate. The right of first refusal in this Section 4 shall not be applicable with respect to any Major Investor, if at the time of such subsequent securities issuance, the Major Investor is not an “accredited investor,” as that term is then defined in Rule 501(a) under the Securities Act.

4.1 Company Notice. The Company shall give notice (the “Offer Notice”) to each Major Investor, stating (a) its bona fide intention to sell such New Securities, (b) the number of such New Securities to be sold and (c) the price and terms, if any, upon which it proposes to sell such New Securities.

4.2 Investor Right. By written notice (the “Investor Notice”) to the Company within twenty (20) days after the Offer Notice is given, each Major Investor may elect to purchase or otherwise acquire, at the price and on the terms specified in the Offer Notice, up to such Major Investor’s Pro Rata Amount. In addition, each Major Investor that elects to purchase or acquire all of its Pro Rata Amount (each, a “Fully Exercising Investor”) may, in the Investor Notice, elect to purchase or acquire, in addition to its Pro Rata Amount, a portion of the New Securities, if any, for which other Major Investors were entitled to subscribe but that are not subscribed for by such Major Investors. The amount of such overallotment that each Fully Exercising Investor shall be entitled to purchase is equal to the proportion that the Common Stock issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of Preferred Stock then held, by such Fully Exercising Investor bears to the Common Stock issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Preferred Stock then held, by all Fully Exercising Investors who wish to purchase such unsubscribed shares. A Major Investor’s election may be conditioned on the consummation of the transaction described in the Offer Notice. The closing of any sale pursuant to this Section 4.2 shall occur on the earlier of one hundred and twenty (120) days after the date that the Offer Notice is given and the date of initial sale of New Securities pursuant to Section 4.3.

4.3 Sale of Securities. If all New Securities referred to in the Offer Notice are not elected to be purchased or acquired as provided in Section 4.2, the Company may, during the ninety (90) day period following the expiration of the periods provided in Section 4.2, offer and sell the remaining unsubscribed portion of such New Securities to any Person or Persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Offer Notice. If the Company does not enter into an agreement for the sale of the New Securities within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such New Securities shall not be offered unless first reoffered to the Major Investors in accordance with this Section 4.

5. ADDITIONAL COVENANTS.

5.1 D&O Insurance. The Company shall use its commercially reasonable efforts to maintain Directors and Officers liability insurance from a financially sound and reputable insurer in an amount and on terms and conditions reasonably satisfactory to the Board, until such time as each of the Board (including at a majority of the Preferred Directors) determines that such insurance should be discontinued. Such policies shall not be cancelable by the Company without prior approval by the Board (including the affirmative approval of at a majority of the Preferred Directors). Notwithstanding any other provision of this Section 5.1 to the contrary, for so long as any Preferred Director is serving on the Board, the Company shall not cease to maintain a Directors and Officers liability insurance policy in an amount of at least $3,000,000 unless approved by a majority of the Preferred Directors, and the Company shall annually, within one hundred twenty (120) days after the end of each fiscal year of the Company, deliver to the Investors a certification that such a Directors and Officers liability insurance policy remains in effect.

5.2 Employee Vesting. Unless otherwise approved by the Board, including the affirmative approval of a majority of the Preferred Directors, all employees, directors, consultants and other service providers of the Company or its subsidiaries who purchase, receive options to purchase, or receive awards of shares of the Company’s capital stock after the date hereof, shall be required to execute restricted stock or option agreements, as applicable, providing for vesting of shares over a four (4) year period, with the first twenty-five percent (25%) of such shares vesting following twelve (12) months of continued employment or service (or the date of grant in the case of a grant to an existing employee or consultant), and the remaining shares vesting in equal monthly installments over the following thirty-six (36) months.

5.3 Employee Agreements. The Company will cause each person now or hereafter employed by it or by any subsidiary (or engaged by the Company or any subsidiary as a consultant/independent contractor) with access to confidential information and/or trade secrets to enter into an employee invention assignment and confidentiality agreement substantially in the form provided to the Investors. In addition, the Company shall not amend, modify, terminate, waive, or otherwise alter, in whole or in part, any of the above-referenced agreements or any restricted stock agreement between the Company and any employee, without approval of the Board, including the affirmative consent of a majority of the Preferred Directors.

5.4 Board Matters; Observer.

5.4.1 Board Meetings and Reimbursement. Unless otherwise determined by the vote of a majority of the directors then in office, the Board of Directors shall meet at least quarterly in accordance with an agreed-upon schedule. The Company shall reimburse the nonemployee directors and observers for all reasonable out-of-pocket travel expenses incurred in connection with attending meetings of the Board.

5.4.2 Nonvoting Frazier Observer. As long as Frazier Life Sciences VIII, L.P. (together with its Affiliates) (“Frazier”) owns at least 1,000,000 shares of Preferred Stock (or an equivalent amount of Common Stock issued upon conversion thereof, and as adjusted for stock splits, consolidations and the like), the Company shall invite a representative of Frazier to attend all meetings of its Board of Directors in a nonvoting observer capacity and, in this respect, shall give such representative copies of all notices, minutes, consents, and other materials that it provides to its directors at the same time and in the same manner as provided to such directors; provided, however, that the Company reserves the right to withhold any information and to exclude such representative from any meeting or portion thereof if access to such information or attendance at such meeting could adversely affect the attorney-client privilege between the Company and its counsel or result in disclosure of trade secrets or a conflict of interest.

5.4.3 Nonvoting AstraZeneca Observer. As long as AstraZeneca owns any shares of Preferred Stock, the Company shall invite a representative of AstraZeneca to attend all meetings of its Board of Directors in a nonvoting observer capacity and, in this respect, shall give such representative copies of all notices, minutes, consents, and other materials that it provides to its directors at the same time and in the same manner as provided to such directors; provided, however, that the Company reserves the right to withhold any information and to exclude such representative from any meeting or portion thereof if access to such information or attendance at such meeting could adversely affect the attorney-client privilege between the Company and its counsel or result in disclosure of trade secrets or a conflict of interest.

5.5 Successor Indemnification. If the Company or any of its successors or assignees consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger, then to the extent necessary, proper provision shall be made so that the successors and assignees of the Company assume the obligations of the Company with respect to indemnification of members of the Board as in effect immediately before such transaction, whether such obligations are contained in the Company’s Bylaws, the Restated Certificate, or elsewhere, as the case may be.

5.6 Indemnification Matters. The Company hereby acknowledges that one (1) or more of the directors nominated to serve on the Board by the Investors (each a “Fund 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 “Fund Indemnitors”). The Company hereby agrees (a) that it is the indemnitor of first resort (i.e., its obligations to any such Fund Director are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by such Fund Director are secondary), (b) that it shall be required to advance the full amount of expenses incurred by such Fund 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 Fund Director to the extent legally permitted and as required by the Restated Certificate or Bylaws of the Company (or any agreement between the Company and such Fund Director), without regard to any rights such Fund Director may have against the Fund Indemnitors, and, (c) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund 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 Fund Indemnitors on behalf of any such Fund Director with respect to any claim for which such Fund Director has sought indemnification from the Company shall affect the foregoing and the Fund 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 Fund Director against the Company.

5.7 Right to Conduct Activities. The Company hereby agrees and acknowledges that Frazier, HBM, Bain Capital Life Sciences, LP (together with its Affiliates) (“BCLS”), OrbiMed Advisors LLC (together with its Affiliates) (“OrbiMed”), BlackRock (together with its Affiliates) (“BlackRock”), RA Capital Healthcare Fund, L.P. (together with its Affiliates) (“RA Capital”), Pivotal BioVentures (together with its Affiliates) (“Pivotal”), Vivo Capital Fund IX, L.P. (together with its Affiliates) (“Vivo”) and Omega Fund VI, LP (together with its Affiliates) (“Omega”, and together with Frazier, HBM, BCLS, OrbiMed, BlackRock, RA Capital, Pivotal, and Vivo, the “Fund Investors”) are professional investment funds, and that AstraZeneca and its Affiliates engage in strategic acquisition and investment transactions in the ordinary course of their business, and as such the Fund Investors and AstraZeneca invest in numerous portfolio companies, some of which may be deemed competitive with the Company’s business (as currently conducted or as currently propose to be conducted). The Company hereby agrees that, to the extent permitted under applicable law, the Fund Investors and AstraZeneca shall not be liable to the Company for any claim arising out of, or based upon, (i) the investment by each Fund Investor or AstraZeneca, respectively, in any entity competitive with the Company, or (ii) actions taken by any partner, stockholder, director, officer or other representative of a Fund Investor or AstraZeneca to assist any such competitive company, whether or not such action was taken as a member of the board of directors of such competitive company or otherwise, and whether or not such action has a detrimental effect on the Company; provided, however, that the foregoing shall not relieve (x) any of the Investors from liability associated with the unauthorized disclosure of the Company’s confidential information obtained pursuant to this Agreement, or (y) any director or officer of the Company from any liability associated with his or her fiduciary duties to the Company; provided, further, that any such representative shall be subject to the requirements of confidentiality and restrictions on use as set forth in this Agreement.

5.8 FCPA. The Company represents that it shall not (and shall not permit any of its subsidiaries or Affiliates or any of its or their respective directors, officers, managers, employees, independent contractors, representatives or agents to) promise, authorize or make any payment to, or otherwise contribute any item of value to, directly or indirectly, to any third party, including any Non-U.S. Official (as (as such term is defined in the U.S. Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”)), in each case, in violation of the FCPA, the U.K. Bribery Act, or any other applicable anti-bribery or anti-corruption law. The Company further represents that it shall (and shall cause each of its subsidiaries and Affiliates to) cease all of its or their respective activities, as well as remediate any actions taken by the Company, its subsidiaries or Affiliates, or any of their respective directors, officers, managers, employees, independent contractors, representatives or agents in violation of the FCPA, the U.K. Bribery Act, or any other applicable anti-bribery or anti-corruption law.

The Company shall use its best efforts to cause any direct or indirect subsidiary, whether now in existence or formed in the future, to comply in all material respects with all applicable laws.

5.9 Qualified Small Business Stock. The Company shall use commercially reasonable efforts to cause the shares of Series A Preferred Stock, as well as any shares into which such shares are converted, within the meaning of Section 1202(f) of the Internal Revenue Code (the “Code”), to constitute “qualified small business stock” as defined in Section 1202(c) of the Code; provided, however, that such requirement shall not be applicable if the Board determines, with the affirmative approval of at least one of the Series A Directors, in its good-faith business judgment, that such qualification is inconsistent with the best interests of the Company. The Company shall submit to its stockholders (including the Investors) and to the Internal Revenue Service any reports that may be required under Section 1202(d)(1)(C) of the Code and the regulations promulgated thereunder. In addition, within twenty (20) business days after any Investor’s written request therefor, the Company shall, at its option, either (i) deliver to such Investor a written statement indicating whether (and what portion of) such Investor’s interest in the Company constitutes “qualified small business stock” as defined in Section 1202(c) of the Code or (ii) deliver to such Investor such factual information in the Company’s possession as is reasonably necessary to enable such Investor to determine whether (and what portion of) such Investor’s interest in the Company constitutes “qualified small business stock” as defined in Section 1202(c) of the Code.

6. TERMINATION.

6.1 Generally. The covenants set forth in Section 2.1, Section 2.2, Section 2.3, Section 4 and Section 5 (other than Subsections 5.5 and 5.6) shall terminate and be of no further force or effect upon the earliest to occur of: (a) immediately prior to 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 Deemed Liquidation Event or a Stock Sale.

7. GENERAL PROVISIONS.

7.1 Successors and Assigns. The rights under this Agreement may be assigned (but only with all related obligations) by a Holder to a transferee of Registrable Securities that (a) is an Affiliate, partner, member, limited partner, retired or former partner, retired or former member, or stockholder of a Holder or such Holder’s Affiliate; (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; (c) after such transfer, holds at least two percent (2%) of the shares of Registrable Securities (or if the transferring Holder owns less than two percent (2%) of the Registrable Securities, then all Registrable Securities held by the transferring Holder); or (d) is a venture capital fund that is controlled by or under common control with one or more general partners or managing partners or managing members of, or shares the same management company with, the Holder; 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 Registrable 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 3.11. For the purposes of determining the number of shares of Registrable Securities held by a transferee, the holdings of a transferee (A) that is an Affiliate, limited partner, retired or former partner, member, retired or former member, or stockholder of a Holder or such Holder’s Affiliate; (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. 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.

7.2 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws.

7.3 Counterparts; Facsimile. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. This Agreement may also be executed and delivered by facsimile or electronic signature and in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

7.4 Titles and Subtitles. The titles and subtitles used in this Agreement are for convenience only and are not to be considered in construing or interpreting this Agreement.

7.5 Notices. All notices, requests, and other communications given, made or delivered pursuant to this Agreement shall be in writing and shall be deemed effectively given, made or delivered upon the earlier of actual receipt or: (a) personal delivery to the party to be notified; (b) when sent, if sent by facsimile or email during the recipient’s normal business hours, and if not sent during normal business hours, then on the recipient’s next business day; (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (d) one (1) business day after the business day of deposit with a nationally recognized overnight courier, freight prepaid, specifying next-day delivery, with written verification of receipt. All communications shall be sent to the respective parties at their addresses as set forth on Schedule A hereto, or to the principal office of the Company and to the attention of the Chief Executive Officer, in the case of the Company, or to such address or facsimile number as subsequently modified by written notice given in accordance with this Section 7.5. If notice is given to the Company, it shall be sent to 2945 Townsgate Road, Suite 110, Westlake Village, CA, 91361, marked “Attention: Chief Executive Officer”; and a copy (which shall not constitute notice) shall also be sent to Fenwick & West LLP, 555 California Street, 12th Floor, San Francisco, California 94104, Attn: Matthew Rossiter, ***@***. If no facsimile number or email address is listed on Schedule A for a party (or above in the case of the Company), notices and communications given or made by facsimile or email shall not be deemed effectively given to such party.

7.6 Amendments and Waivers. This Agreement may only be amended or terminated and the observance of any term hereof may be waived (either generally or in a particular instance, and either retroactively or prospectively) only by a written instrument executed by the Company and the Requisite Preferred Majority; provided, that (i) the Company may in its sole discretion waive compliance with Section 3.12 (and the Company’s failure to object promptly in writing after notification of a proposed assignment allegedly in violation of Section 3.12 shall be deemed to be a waiver); (ii) any provision hereof may be waived by any waiving party on such party’s own behalf, without the consent of any other party; (iii) the Company may, without the consent or approval of any other party hereto, cause additional persons to become party to this Agreement as Investors or Lenders pursuant to Section 7.14 hereto and amend Schedule A hereto accordingly; (iv) if, after giving effect to any waiver of Section 4 or any provision pertaining to Section 4 with respect to a particular transaction, a Major Investor purchases securities in such transaction or issuance (such Major Investor, a “Participating Investor”), then each Major Investor shall be permitted to participate in such offering on a pro rata basis (based on the level of participation of the Major Investor purchasing the largest portion of such Major Investor’s Pro Rata Amount) in accordance with the other provisions (including notice and election periods) set forth in Section 4; and (v) Section 5.4.3 and clause (b) of the definition of “Major Investor” shall not be amended or waived without the consent of AstraZeneca. 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 Major Investor without the written consent of such Major Investor, unless such amendment,

termination, or waiver applies to all Major Investors in the same fashion. Further, this Agreement may not be amended, and no provision hereof may be waived, in each case, in any way which would adversely affect the rights of the Key Holders hereunder in a manner disproportionate to any adverse effect such amendment or waiver would have on the rights of the Investors hereunder, without also the written consent of the holders of a majority of the Registrable Securities held by the Key Holders; provided, however, that the grant to third parties of piggyback registration rights under Section 3.2 hereof shall not be deemed to be an adverse change to the piggyback registration rights of the Key Holders under this Agreement and shall not require the consent of the Key Holders. Any amendment, termination, or waiver effected in accordance with this Section 7.6 shall be binding on each party hereto and all of such party’s successors and permitted assigns, regardless of whether or not any such party, successor or assignee entered into or approved such amendment, termination, or waiver. 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. Notwithstanding the foregoing, Section 7.6(iv) and this last sentence of Section 7.6 may be amended and the observance of any term thereof may be waived (either generally or in a particular instance, and either retroactively or prospectively) only by a written instrument executed by the holders of a majority of the Registrable Securities then outstanding held by the Major Investors.

7.7 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.

7.8 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.

7.9 Entire Agreement. This Agreement (including any Schedules and Exhibits 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 and replaced with this Agreement.

7.10 Third Parties. Nothing in this Agreement, express or implied, is intended to confer upon any person, other than the parties hereto and their successors and assigns, any rights or remedies under or by reason of this Agreement.

7.11 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.

7.12 Dispute Resolution; Waiver of Jury Trial. The parties (a) hereby irrevocably and unconditionally submit to the jurisdiction of the federal or state courts located in the Northern District of California for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (b) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in the federal or state courts located in the Northern District of California, and (c) 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 a party is not subject to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution based upon judgment or order of such court(s), that any suit, action or proceeding arising out of or based upon this Agreement commenced in the federal or state courts located in the Northern District of California is brought in an inconvenient forum, that the venue of such suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court. Should any party commence a suit, action or other proceeding arising out of or based upon this Agreement in a forum other than the federal or state courts located in the Northern District of California, or should any party otherwise seek to transfer or dismiss such suit, action or proceeding from such court(s), that party shall indemnify and reimburse the other party for all legal costs and expenses incurred in enforcing this provision.

EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS, THE SECURITIES OR THE SUBJECT MATTER HEREOF OR THEREOF. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION, INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS (INCLUDING NEGLIGENCE), BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. 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.

7.13 Attorneys’ Fees. If any action at law or in equity is necessary to enforce or interpret the terms of this Agreement, the non-prevailing party shall pay all costs and expenses incurred by the prevailing party, including, without limitation, all reasonable attorneys’ fees.

7.14 Additional Investors and Lenders. Notwithstanding anything to the contrary contained herein, if the Company issues additional shares of the Company’s Series C Preferred Stock after the date hereof, any purchaser of such shares of Series C Preferred Stock may become a party to this Agreement by executing and delivering an additional counterpart signature page to this Agreement, and thereafter shall be deemed an “Investor” for all purposes hereunder. In addition, notwithstanding anything to the contrary contained herein, if the

Company issues any Lender Warrant, any recipient of a Lender Warrant may become a party to this Agreement by executing and delivering an additional counterpart signature page to this Agreement, and thereafter shall be deemed a “Lender” for all purposes hereunder. No action or consent by the Investors shall be required for such joinder to this Agreement by such additional Investor or Lender, so long as such additional Investor or Lender has agreed in writing to be bound by all of the obligations as an “Investor” or a “Lender” hereunder, as applicable.
