Upon Gilead’s request, including any such request made prior to delivery of an Additional Shares Purchase Notice, the Company shall promptly provide Gilead with information and assistance as may be reasonably necessary for Gilead to make such determination.

other promptly informed of all communications with and providing copies of all written communications, from and to any Antitrust Authority, and sharing drafts of written submissions to any Antitrust Authority in advance of submission and taking comments of the other into account in good faith; however, the parties may redact submissions for privilege and the parties also may request that distribution of submissions be limited to outside counsel only and (b) conferring with each other regarding contacts with and responses to, and permitting the other to participate in all meetings and video conferences or substantive telephone conversations with, to the extent not prohibited by, the FTC, DOJ or other any other Antitrust Authority; provided that subject to its undertakings and obligations under this Section 2.4 to take into consideration in good faith the Company’s views, suggestions and comments regarding the strategy to be pursued for obtaining all required Antitrust Approvals, Gilead shall lead the strategy to obtain all such approvals, and if there is a dispute between Gilead and the Company, the final determination as to the appropriate course of action shall be made by Gilead. Each Party shall be responsible for its own costs and expenses associated with obtaining any required Antitrust Approvals, but (i) Gilead shall be responsible for payment of all fees to any Antitrust Authority with respect to antitrust filings made pursuant to the HSR Act or foreign antitrust law, and (ii) [***].

3.1.8 SEC Reports, Financial Statements.

(a) The Common Stock is registered pursuant to Section 12(b) or 12(g) of the Exchange Act. The Company has delivered or made available (by filing on the Commission’s electronic data gathering and retrieval system (XXXXX))

to Gilead complete copies of its SEC Reports since March 14, 2018. As of its date, each SEC Report complied in all material respects with the requirements of the Exchange Act, and other Laws applicable to it, and, as of its date, such SEC Report did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. No inquiries or any other investigation conducted by or on behalf of Gilead or its representatives or counsel will modify, amend or affect Gilead’s right to rely on the truth, accuracy and completeness of the SEC Reports and the Company’s representations and warranties contained in this Agreement.

(b) The financial statements, together with the related notes and schedules, of the Company included in the SEC Reports comply as to form in all material respects with all applicable accounting requirements and the published rules and regulations of the Commission and all other applicable rules and regulations with respect thereto. Such financial statements, together with the related notes and schedules, have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) applied on a consistent basis during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto or (ii) in the case of unaudited interim statements, to the extent they may not include footnotes or may be condensed or summary statements), and fairly present in all material respects the financial condition of the Company and its consolidated subsidiaries as of the dates thereof and the results of operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments).

(c) The Common Stock is listed on NYSE, and the Company has taken no action designed to, or that to its knowledge is likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act or delisting the Common Stock from NYSE. As of the date of this Agreement, the Company has not received any notification that, and has no knowledge that, the Commission or NYSE is contemplating terminating such registration or listing.

3.1.9 Disclosure Controls. The Company and each of its subsidiaries maintain systems of internal accounting controls sufficient to provide reasonable assurance that (a) transactions are executed in accordance with management’s general or specific authorizations; (b) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability; (c) access to assets is permitted only in accordance with management’s general or specific authorization; and (d) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company’s internal control over financial reporting is effective and the Company is not aware of any material weaknesses in its internal control over financial reporting. Since the date of the latest audited financial statements of

the Company, there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company has established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15 and 15d-15) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company and each of its subsidiaries is made known to the certifying officers by others within those entities, particularly during the period in which the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of a date within 90 days prior to the filing date of the Form 10-K for the fiscal year most recently ended (such date, the “Evaluation Date”). The Company presented in its Form 10-K for the fiscal year most recently ended the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date and the disclosure controls and procedures are effective. Since the Evaluation Date, there have been no significant changes in the Company’s internal controls (as such term is defined in Item 307(b) of Regulation S-K under the Securities Act) or, to the Company’s knowledge, in other factors that could significantly affect the Company’s internal controls.

5.4. Amendments; Waivers. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the parties hereto unless reduced to writing and signed by an authorized officer of each party. Any delay in enforcing a party’s rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver relating to a particular matter for a particular period of time.

5.5. Termination. This Agreement shall simultaneously and automatically terminate in the event that (a) the Collaboration Agreement terminates in its entirety for any reason or (b) the Company consummates any merger, consolidation or similar transaction, unless immediately following the consummation of such transaction, the stockholders of the Company immediately prior to the consummation of such transaction continue to hold, as a result of their holding of outstanding Common Stock and other securities entitled to vote for the election of directors of the Company immediately prior to the consummation of such transaction, in aggregate more than 50% of the outstanding Common Stock and other securities entitled to vote for the election of directors of the surviving or resulting entity in such transaction. In addition, after the Second Closing, Gilead may terminate this Agreement upon [***] days’ prior written notice to the Company. If not earlier terminated, this Agreement shall automatically terminate upon the later of (a) the expiration of the Exercise Period and (b) the occurrence of all Additional Closings with respect to sales of Additional Shares under any Additional Shares Purchase Notice(s) made and duly given on or prior to the expiration of the Exercise Period.

5.6. Construction; Headings. The terms “includes,” “including,” “include” and derivative forms of them shall be deemed followed by the phrase “without limitation” (regardless of whether it is actually written (and drawing no implication from the actual inclusion of such phrase in some instances after such terms but not others)) and the term “or” has the inclusive meaning represented by the phrase “and/or” (regardless of whether it is actually written (and drawing no implication from the actual use of the phrase “and/or” in some instances but not in others)). Unless specified to the contrary, references to Articles or Sections shall refer to the particular Articles or Sections of or to this Agreement. The word “day,” “quarter” or “year” (and derivatives thereof, e.g., “quarterly”) shall mean a calendar day, calendar quarter or calendar year unless otherwise specified. The word “hereof,” “herein,” “hereby” and derivative or similar word refers to this Agreement. The words “will” and “shall” shall have the same obligatory meaning. Provisions that require that a party or parties hereunder “agree,” “consent” or “approve” or the like shall require that such agreement, consent or approval be specific and in writing, whether by written agreement, letter or otherwise. Words of any gender include the other gender. Words using the singular or plural number also include the plural or singular number, respectively. References to any specific law or article, section or other division thereof, shall be deemed to include the then-current amendments or any replacement law thereto, and any rules and regulations promulgated thereunder. All dollar-denominated amounts herein are in United States dollars. This Agreement has been prepared jointly and shall not be strictly construed against either party. Ambiguities, if any, in this Agreement shall not be construed against either party, irrespective of which party may be deemed to have authored the ambiguous provision. The headings of each Article and Section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Article or Section.

5.7. Further Assurances. Each party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

5.8. Successors and Assigns. This Agreement may not be assigned by a party hereto without the prior written consent of the Company or Gilead, as applicable, provided, however, that Gilead may assign its rights and delegate its duties hereunder in whole or in part to an Affiliate

without the prior written consent of the Company, provided such assignee agrees in writing to be bound by the provisions hereof that apply to Gilead. The provisions of this Agreement shall inure to the benefit of and be binding upon the respective permitted successors and assigns 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 permitted successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement.

5.9. Third Party Beneficiaries. This Agreement is not intended to and shall not be construed to give any third party any interest or rights (including any third party beneficiary rights) with respect to or in connection with any agreement or provision contained herein or contemplated hereby.

5.10. Governing Law. This Agreement shall be governed by and construed under the substantive laws of the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

5.11. Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of Gilead and the Company will be entitled to specific performance under this Agreement. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in this Agreement and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

5.12. WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.

5.13. Attorneys’ Fees. In the event that any action is instituted under or in relation to this Agreement, including without limitation to enforce any provision in this Agreement, each party shall bear its own fees, costs and expenses of enforcing any right of such party under or with respect to this Agreement.

5.14. Survival. The representations and warranties contained herein shall survive the Closings and the delivery of the Shares and any termination of this Agreement.

5.15. Counterparts. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf

such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

5.16. Severability. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by an arbitrator or by any court of competent jurisdiction from which no appeal can be or is taken, the provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the parties when entering into this Agreement may be realized.

5.17. Investor Rights Agreement. For clarity, the parties agree and acknowledge that (a) this Amended and Restated Common Stock Purchase Agreement is the “Purchase Agreement” under and as defined in the Investor Rights Agreement and (b) the Second Closing Shares constitute Registrable Securities thereunder (subject to the limitations set forth in Section 1.1.46(a) through (c) thereof).
