ARTICLE 2
BOARD MATTERS

2.1 Board Designation Rights. Subject to the terms and conditions of this Article 2, including the termination provisions of Section 2.4, Gilead shall have the right to designate three (3) individuals to be appointed to the Board (“Proposed Gilead Designees”). Such individuals shall be (a) qualified and suitable to serve as a member of the Board under all applicable corporate governance policies and guidelines of the Company and the Board and applicable legal, regulatory and stock market requirements, as determined in good faith by the Board, and (b) reasonably acceptable to a majority of the other members of the Board and the Company’s independent auditors (such qualifications in clauses (a) and (b), the “Board Qualifications”). Gilead will take all necessary action to cause the Proposed Gilead Designees to make themselves reasonably available for interviews, to consent to the Company’s standard reference and background checks and other investigations and to provide such information (including information necessary to determine the individual’s independence status under applicable requirements and institutional investor guidelines as well as information necessary to determine any disclosure obligations of the Company) as the Board may reasonably request, provided that such interviews, investigations and information requested of the Proposed Gilead Designees is materially consistent with such similar requests made of all current members of the Board or other candidates for nomination to the Board. If, following such process, the Board in good faith determines that any Proposed Gilead Designee does not meet the Board Qualifications, such Proposed Gilead Designee shall cease to be a Proposed Gilead Designee, and Gilead shall have the right to designate another individual as a Proposed Gilead Designee (which process may be repeated until such time as the Board in good faith determines that a Gilead Designee meets the Board Qualifications). Once the Board in good faith determines that a Proposed Gilead Designee meets the Board Qualifications, such Proposed Gilead Designee shall be a “Gilead Designee.” Any individual who becomes a Gilead Designee shall retain such status for so long as they are a member of the Board. Notwithstanding any other policy or practice of the Company applicable to the Board, no Gilead Designee is entitled to any additional compensation for services on the Board as a Gilead Designee.

2.2 Appointment of Directors. Xxxxxx Xxxxxx and Xxxxxxx Xxxxxxx are the initial Gilead Designees, and the Board has determined that each of them meets the Board Qualifications. The Board shall appoint each of the initial Gilead Designees to be a member of the Board effective on the Closing Date or as soon thereafter as such appointment can be made without causing less than a majority of the members of the Board to be Independent Directors. Xxxxxxx Xxxxxxx is the third Gilead Designee, and the Board has determined that she meets the Board Qualifications. The Board shall appoint such third Gilead Designee to be a member of the Board effective on the Fourth Closing Date (as defined in the Purchase Agreement), or as soon thereafter as such appointment can be made without causing less than a majority of the members of the Board to be Independent Directors. If the appointment of a Gilead Designee must be deferred as described above, the Company shall use all commercially reasonable efforts, including the recruitment of additional Independent Directors, to enable such appointment to be made at the earliest practicable date, and in any event, not later than the six-month anniversary of the Effective Date. The Board shall assign each of the Gilead Designees to one of the three Board classes at the time of their appointment in accordance with the Company’s Amended and Restated Certificate of Incorporation and will endeavor to assign the Gilead Designees to different classes. Subject to Section 2.4, at the end of the term of each Gilead Designee, such Gilead Designee shall be nominated for re-election as a director, provided that such Gilead Designee continues to meet the Board Qualifications, as part of the slate proposed by the Board that is included in the proxy statement (or consent solicitation or similar document) of the Company relating to the election of the Board, and the Company will use all commercially reasonable efforts to cause the election of such Gilead Designee to the Board (including providing the same level of support as is provided for other nominees of the Company to the Board). Until the First Designee Termination Date, Second Designee Termination Date or Final Designee Termination Date, as applicable, for so long as each such Gilead Designee satisfies the Board Qualifications, the Company shall not take any action that precludes the submission of each such Gilead Designee to the stockholders of the Company for election to the Board. In the event that a Gilead Designee ceases to be a member of the Board (whether due to death, resignation or otherwise), Gilead may, subject to Section 2.4, select another person (who the Company may require to be an Independent Director, if appointed, if the Gilead Designee who ceased to be a member of the Board was an Independent Director and the selection of a director who is not independent would cause the Company to not be in compliance with the independence rules of the Exchange Act or NYSE) as a Proposed Gilead Designee to fill the vacancy created thereby, and, following the application of the provisions of Section 2.1 above, the Company shall act to appoint such resulting Gilead Designee to fill such vacancy.

2.3 Policies and Requirements. The Gilead Designees shall be subject to the policies and requirements of the Company and the Board, including the corporate governance guidelines of the Board and the Company’s Code of Conduct and Ethics, in a manner consistent with the application of such policies and requirements to other members of the Board. The Company shall reimburse the expenses of the Gilead Designees consistent with the Company’s policies on business expense reimbursement and shall indemnify them and provide the Gilead Designees with director and officer liability insurance to the same extent it indemnifies and provides insurance for the other non-employee members of the Board pursuant to its organizational documents, applicable law or otherwise.

2.4 Termination of Board Designation Rights. From and after the First Designee Termination Date, (a) Gilead shall no longer be entitled to designate more than two Gilead Designees, and (b) the Company will no longer be obligated to nominate for re-election as a director a Gilead Designee, if, following the appointment of such Gilead Designee to the Board there would be more than two Gilead Designee serving on the Board. At any time thereafter when there are three Gilead Designees serving on the Board, the Company may request in writing that one of such Gilead Designees resign from the Board, and Gilead shall cause a Gilead Designee of its choosing to resign from the Board within five (5) Business Days following such written request. From and after the Second Designee Termination Date, (a) Gilead shall no longer be entitled to designate more than one Gilead Designee, and (b) the Company will no longer be obligated to nominate for re-election as a director a Gilead Designee, if, following the appointment of such Gilead Designee to the Board there would be more than one Gilead Designee serving on the Board. At any time thereafter when there are two Gilead Designees serving on the Board, the Company may request in writing that one of such Gilead Designees resign from the Board, and Gilead shall cause a Gilead Designee of its choosing to resign from the Board within five (5) Business Days following such written request. From and after the Final Designee Termination Date (i) Gilead shall no longer be entitled to designate any Gilead Designees and (ii) at any time when there is any Gilead Designee serving on the Board, the Company may request in writing that such Gilead Designee resign from the Board, and Gilead shall cause such Gilead Designee to resign from the Board within five (5) Business Days following such written request. After the later to occur of the Final Designee Termination Date and the date all Gilead Designees have resigned from the Board in accordance with this Section 2.4, all rights of Gilead and obligations of the Company under this Article 2 shall terminate, provided that, for clarity, the Company shall continue to indemnify and provide any former Gilead Designees with director and officer liability insurance to the same extent it indemnifies and provides insurance for the other non-employee past members of the Board pursuant to its organizational documents, applicable law or otherwise.

2.5 Board Size; Compensation; Scientific Committee; Scientific Advisory Board. Within 30 days following the date hereof, the Company shall:

2.5.1          Take all such actions necessary to reduce the size of the Board from 12 directors to 11 directors and accept the resignations from the Board of Xxxxxxxx Xxxxxxx and Xxxx Xxxx in connection therewith; and

2.5.2          Establish a Science Committee of the Board to oversee, on behalf of the Board, activities related to the Company’s products and product candidates (both commercial and clinical) (the “Science Committee”).

From and following establishment of the Science Committee, the Company shall cause each Gilead Designee with an advanced science degree (each, a “Gilead Scientific Designee”) to be a member of the Science Committee. In addition, from and following the Fourth Closing Date, Gilead shall be entitled to appoint up to two members of Gilead’s senior leadership team with an advanced science degree or scientific qualifications (each, a “Gilead SAB Designee”) to serve on the Company’s Scientific Advisory Board (the “SAB”), with Xxxxx Xxxxxxx serving as the initial designee of Gilead to the SAB. For the avoidance of doubt, no Gilead Scientific Designee or Gilead SAB Designee is entitled to additional compensation for service on the Science Committee or the SAB.

Gilead hereby agrees that it and its Controlled Affiliates will not, without the prior written consent of any managing underwriter, during the period commencing on the date of the final prospectus relating to the registration by the Company of shares of its Common Stock or any other Equity Securities under the Securities Act on a registration statement on Form S-3 in an underwritten public offering of Common Stock, and ending on the date specified by the Company and the managing underwriter, provided that such date shall not be later than 90 days following the date of such final prospectus, (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 (whether such shares or any such securities are then owned by Gilead or its Affiliates or are thereafter acquired) 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 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 5.1 shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, and shall be applicable to Gilead and its Affiliates only if all executive officers and directors of the Company are subject to the same restrictions. The underwriters in connection with such registration are intended third party beneficiaries of this Section 5.1 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Gilead further agrees to execute and cause its Controlled Affiliates to execute such agreements as may be reasonably requested by the underwriters in connection with such registration that are consistent with this Section 5.1 or that are necessary to give further effect thereto. The provisions of this Section 5.1 shall automatically terminate upon the date upon which both (a) there is no Gilead Designee serving on the Board and Gilead, together with its Affiliates, collectively, do not, directly or indirectly, own outstanding shares of Common Stock representing at least [***]% of the Company Capitalization.

5.2          Restrictions on Transfer.

5.2.1          Subject to Article 6, the Shares will not be sold, pledged, or otherwise transferred, and the Company will not recognize and will issue stop-transfer instructions to its transfer agent with respect to any such sale, pledge, or transfer, except upon the conditions specified in this Section 5.2.1, which conditions are intended to ensure compliance with the provisions of the Securities Act. Each Holder, if effecting a transfer of Shares other than a sale pursuant to Commission Rule 144 or sale pursuant to a registration statement under the Securities Act, will cause any proposed purchaser, pledgee, or transferee of the Shares to agree to take and hold such securities subject to the provisions and upon the conditions specified in this Section 5.2.1.

5.2.2          Gilead understands and agrees that the Shares (or uncertificated interests in the Shares) will bear a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of the Shares):

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER APPLICABLE SECURITIES LAWS, OR UNLESS OFFERED, SOLD, PLEDGED, HYPOTHECATED OR TRANSFERRED PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS. THE COMPANY SHALL BE ENTITLED TO REQUIRE AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED TO THE EXTENT THAT SUCH OPINION IS REQUIRED PURSUANT TO THAT CERTAIN COMMON STOCK PURCHASE AGREEMENT UNDER WHICH THE SECURITIES WERE ISSUED.

5.2.3          Each Holder consents to the Company making a notation in its records and giving instructions to any transfer agent of the Common Stock in order to implement the restrictions on transfer set forth in this Section 5.2.

5.2.4          Each Holder agrees to comply in all respects with the provisions of this Section 5.2. Before any proposed sale, pledge, or transfer of any Restricted Securities that is not effected pursuant to Commission Rule 144, unless there is in effect a registration statement under the Securities Act covering the proposed transaction, the Holder will give notice to the Company of its intention to effect such sale, pledge, or transfer. Each such notice will describe the manner and circumstances of the proposed sale, pledge, or transfer in sufficient detail and, if reasonably requested by the Company, will be accompanied at such Holder’s expense by either: (i) a written opinion of legal counsel who will, and whose legal opinion will, 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 Commission 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 Commission 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 will 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 and such securities will no longer constitute Restricted Securities for purposes of this Agreement. The Company will not require such a legal opinion or “no action” letter in any transaction in which such Holder distributes Restricted Securities to an Affiliate of such Holder for no consideration; provided that each such transferee agrees in writing to be subject to the terms of this Section 5.2. Each certificate or instrument evidencing the Restricted Securities transferred as above provided will bear, except if such transfer is made pursuant to Commission Rule 144, the appropriate restrictive legend set forth in Section 5.2.2, except that such certificate will 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.

5.3 Anti-Dilution. If, at any time during the Exercise Period, the Company offers new shares of Common Stock (or any new securities convertible into or exercisable or exchangeable for new shares of Common Stock) to any person or entity other than Gilead or its Affiliates (other than (a) to current or future employees, consultants, directors and/or officers of the Company or its Affiliates in the form of equity-based incentive or compensation or the exercise or vesting of such incentive or compensation or (b) in an “at-the-market” offering) in a public offering for cash, the Company shall permit Gilead, but Gilead shall not be required, to invest either (at the Company’s election) in such offering or in a concurrent private placement in accordance with applicable securities laws and stock exchange rules, or both (in each case, on the same terms as the other investors in such public offering and at a price per share or security equal to the price paid by the other investors in the public offering), in either case (or in combination) in an aggregate amount pro rata to its then percentage ownership based on the Company Capitalization immediately prior to the consummation of such offering(s). For purposes of determining Gilead’s pro rata share of the Company Capitalization in this Section 5.3, shares of Common Stock issuable upon conversion, exercise or exchange of any securities convertible into or exercisable or exchangeable for new shares of Common Stock (other than securities issued to employees, consultants, directors and/or officers of the Company or its Affiliates in the form of equity-based incentive or compensation) held by Gilead and all other holders shall be deemed to be outstanding. Notwithstanding the foregoing, in no event shall Gilead be permitted to purchase any securities pursuant to this Section 5.3 if, after giving effect to such purchase, Gilead and its Controlled Affiliates, and any other party acting in concert with Gilead or any of its Controlled Affiliates, would, together in the aggregate, directly or indirectly Beneficially Own a number of shares of Common Stock greater than 35% of the Company Capitalization on such date, rounded down to the nearest whole share.

5.4 Open Market Purchases. At any time during the Exercise Period, Gilead shall be permitted to acquire shares of Common Stock through open market purchases so long as, after giving effect to such acquisition, Gilead and its Controlled Affiliates, and any other party acting in concert with Gilead or any of its Controlled Affiliates, would, together in the aggregate, not directly or indirectly Beneficially Own a number of shares of Common Stock greater than 35% of the Company Capitalization on such date, rounded down to the nearest whole share.

ARTICLE 6
REGISTRATION RIGHTS

6.1          Registration Statements.

6.1.1          On or before October 31, 2022 (the “Filing Date”), the Company shall file a registration statement covering the resale of the Registrable Securities with the Commission for an offering to be made on a continuous basis pursuant to Commission Rule 415, or if Commission Rule 415 is not available for offers and sales of the Registrable Securities, by such other means of distribution of Registrable Securities as Gilead may reasonably specify (the “Initial Registration Statement”). The Initial Registration Statement shall be on Form S-3 (except if the Company is ineligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on another appropriate form) and the Company shall effect the registration, qualifications or compliances (including, without limitation, the execution of any required undertaking to file post-effective amendments, appropriate qualifications or exemptions under applicable blue sky or other state securities laws and appropriate compliance with applicable securities laws, requirements or regulations) as promptly as possible after the filing thereof, but in any event prior to the date which is 75 days in the event of no review by the Commission, or 120 days in the event of a review by the Commission, after the expiration of the Lock-Up Period. For purposes of clarification, any failure by the Company to file the Initial Registration Statement by the Filing Date or to effect such Registration Statement within such 75 or 120 days, as applicable, after the expiration of the Lock-Up Period shall not otherwise relieve the Company of its obligations to file or effect the Initial Registration Statement as set forth above in this Section 6.1.1. In the event the Commission informs the Company that all of the Registrable Securities cannot, as a result of the application of Commission Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (a) inform each Holder thereof, (b) use its reasonable efforts to file amendments to the Initial Registration Statement as required by the Commission and/or (c) withdraw the Initial Registration Statement and file a new registration statement (a “New Registration Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the Commission, on Form S-3 or, if the Company is ineligible to register for resale the Registrable Securities on Form S-3, such other form available to register for resale the Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its reasonable efforts to advocate with the Commission for the registration of all of the Registrable Securities. In the event the Company amends the Initial Registration Statement or files a New Registration Statement, as the case may be, under clauses (b) or (c) above, the Company will use its reasonable efforts to file with the Commission, as promptly as allowed by the Commission, one or more registration statements on Form S-3 or, if the Company is ineligible to register for resale the Registrable Securities on Form S-3, such other form available to register for resale those Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended, or the New Registration Statement (the “Remainder Registration Statements”).

6.1.2          As soon as reasonably practicable, but in no event later than 30 days after each Additional Closing Date that follows the expiration of the Lock-Up Period (each, an “Additional Filing Date”), the Company shall file a registration statement covering the resale of the additional Registrable Securities purchased on each such Additional Closing Date with the Commission for an offering to be made on a continuous basis pursuant to Commission Rule 415, or if Commission Rule 415 is not available for offers and sales of the Registrable Securities, by such other means of distribution of Registrable Securities as Gilead may reasonably specify (each, an “Additional Registration Statement”). For purposes of this Agreement, the term Additional Closing Date shall include the Fourth Closing Date, as defined in the Purchase Agreement. Each Additional Registration Statement shall be on Form S-3 (except if the Company is ineligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on another appropriate form) and the Company shall effect the registration, qualifications or compliances (including, without limitation, the execution of any required undertaking to file post-effective amendments, appropriate qualifications or exemptions under applicable blue sky or other state securities laws and appropriate compliance with applicable securities laws, requirements or regulations) as promptly as possible after the filing thereof, but in any event prior to the date which is 75 days in the event of no review by the Commission, or 120 days in the event of a review by the Commission, after the applicable Additional Closing Date. For purposes of clarification, any failure by the Company to file an Additional Registration Statement by the applicable Additional Filing Date or to effect such Registration Statement within such 75 or 120 days, as applicable, after the applicable Additional Closing Date shall not otherwise relieve the Company of its obligations to file or effect the applicable Additional Registration Statement as set forth above in this Section 6.1.2. In the event the Commission informs the Company that all of the additional Registrable Securities cannot, as a result of the application of Commission Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (a) inform each Holder thereof, (b) use its reasonable efforts to file amendments to the Additional Registration Statement as required by the Commission and/or (c) withdraw the Additional Registration Statement and file a new registration statement (a “New Additional Registration Statement”), in either case covering the maximum number of additional Registrable Securities permitted to be registered by the Commission, on Form S-3 or, if the Company is ineligible to register for resale the additional Registrable Securities on Form S-3, such other form available to register for resale the additional Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment or New Additional Registration Statement, the Company shall be obligated to use its reasonable efforts to advocate with the Commission for the registration of all of the additional Registrable Securities. In the event the Company amends the Additional Registration Statement or files a New Additional Registration Statement, as the case may be, under clauses (b) or (c) above, the Company will use its reasonable efforts to file with the Commission, as promptly as allowed by the Commission, one or more registration statements on Form S-3 or, if the Company is ineligible to register for resale the additional Registrable Securities on Form S-3, such other form available to register for resale those additional Registrable Securities that were not registered for resale on the Additional Registration Statement, as amended, or the New Additional Registration Statement (the “Remainder Additional Registration Statements”).

6.1.3          Any provision hereof to the contrary notwithstanding, until the Existing Investors’ Rights Agreement Termination Date, the Company shall not be obligated to cause any registration statement hereunder to become effective within 120-days of the effective date of any registration effected pursuant to Section 1.2 of the Existing Investors’ Rights Agreement.

6.2          Registration Expenses. All Registration Expenses incurred in connection with any registration, qualification, exemption or compliance pursuant to Section 6.1 shall be borne by the Company. All Selling Expenses relating to the sale of securities registered by or on behalf of each Holder shall be borne by such Holder on the basis of the number of securities so registered.

6.3          Company Obligations. In the case of the registration, qualification, exemption or compliance effected by the Company pursuant to this Agreement, the Company shall, upon reasonable request, inform each Holder as to the status of such registration, qualification, exemption and compliance.

6.3.1          At its expense the Company shall:

(a)

except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which the Company determines to obtain, continuously effective with respect to a Holder, and to keep the applicable Registration Statement free of any material misstatements or omissions, until the earlier of the following: (i) the date on which all Registrable Securities have been sold pursuant to a Registration Statement or (ii) the date all Shares held by such Holder may be sold under Commission Rule 144 without being subject to any volume, manner of sale or publicly available information requirements. The period of time during which the Company is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period.”

(b)

advise the Holders within five (5) Business Days:

(A)          when a Registration Statement or any amendment thereto has been filed with the Commission and when such Registration Statement or any post-effective amendment thereto has become effective;

(B)          of any request by the Commission for amendments or supplements to any Registration Statement or the prospectus included therein or for additional information;

(C)          of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(D)          of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(E)          of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading;

(c)

use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(d)

if a Holder so requests in writing, promptly furnish to each such Holder, without charge, at least one (1) copy of each Registration Statement and each post-effective amendment thereto, including financial statements and schedules, and, if explicitly requested, all exhibits in the form filed with the Commission;

(e)

during the Registration Period, promptly deliver to each such Holder, without charge, as many copies of each prospectus included in a Registration Statement and any amendment or supplement thereto as such Holder may reasonably request in writing; and the Company consents to the use, consistent with the provisions hereof, of the prospectus or any amendment or supplement thereto by each of the selling Holders of Registrable Securities in connection with the offering and sale of the Registrable Securities covered by a prospectus or any amendment or supplement thereto;

(f)

during the Registration Period, if a Holder so requests in writing, deliver to each Holder, without charge, (i) one (1) copy of the following documents, other than those documents available via XXXXX: (A) its annual report to its stockholders, if any (which annual report shall contain financial statements audited in accordance with generally accepted accounting principles in the United States of America by a firm of certified public accountants of recognized standing), (B) if not included in substance in its annual report to stockholders, its annual report on Form 10-K (or similar form), (C) its definitive proxy statement with respect to its annual meeting of stockholders, (D) each of its quarterly reports to its stockholders, and, if not included in substance in its quarterly reports to stockholders, its quarterly report on Form 10-Q (or similar form), and (E) a copy of each full Registration Statement (the foregoing, in each case, excluding exhibits); and (ii) if explicitly requested, all exhibits excluded by the parenthetical to the immediately preceding clause (E);

(g)

prior to any public offering of Registrable Securities pursuant to any Registration Statement, promptly take such actions as may be necessary to register or qualify or obtain an exemption for offer and sale under the securities or blue sky laws of such United States jurisdictions as any such Holders reasonably request in writing, provided that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction, and do any and all other acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Registrable Securities covered by any such Registration Statement;

(h)

upon the occurrence of any event contemplated by Section 6.3.1(b)(E) above, except for such times as the Company is permitted hereunder to suspend the use of a prospectus forming part of a Registration Statement, the Company shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(i)

otherwise use its commercially reasonable efforts to comply in all material respects with all applicable rules and regulations of the Commission which could affect the sale of the Registrable Securities;

(j)

use its commercially reasonable efforts to cause all Registrable Securities to be listed on each securities exchange or market, if any, on which Equity Securities issued by the Company have been listed;

(k)

use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Registrable Securities contemplated hereby and to enable the Holders to sell Registrable Securities under Commission Rule 144;

(l)

provide to Gilead and its representatives, if requested, the opportunity to conduct a reasonable inquiry of the Company’s financial and other records during normal business hours and make available its officers, directors and employees for questions regarding information which such Purchaser may reasonably request in order to fulfill any due diligence obligation on its part; and

(m)

permit counsel for Gilead to review any Registration Statement and all amendments and supplements thereto (other than supplements to a Registration Statement on Form S-1 solely for the purpose of incorporating other filings with the Commission into such Registration Statement and other than an amendment to a Registration Statement on Form S-1 on Form S-3 for the purpose of converting such Registration Statement into a Registration Statement on Form S-3), within two (2) Business Days prior to the filing thereof with the Commission;

provided that, in the case of clauses (l) and (m) above, the Company shall not be required (a) to delay the filing of any Registration Statement or any amendment or supplement thereto as a result of any ongoing diligence inquiry by or on behalf of a Holder or to incorporate any comments to any Registration Statement or any amendment or supplement thereto by or on behalf of a Holder if such inquiry or comments would require a delay in the filing of such Registration Statement, amendment or supplement, as the case may be, or (b) to provide, and shall not provide, Gilead or its representatives with material, non-public information unless Gilead agrees in writing to receive such information and enters into a written confidentiality agreement with the Company in a form reasonably acceptable to the Company.

6.4          No Right to Enjoin. The Holders shall have no right to take any action to restrain, enjoin or otherwise delay any registration pursuant to Section 6.1 hereof as a result of any controversy that may arise with respect to the interpretation or implementation of this Agreement.

6.5          Indemnification.

6.5.1          To the extent permitted by law, the Company shall indemnify each Holder and each Person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which any registration that has been effected pursuant to this Agreement, against all claims, losses, damages and liabilities (or action in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 6.5.3 below), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, prospectus, any amendment or supplement thereof, or other document incident to any such registration, qualification or compliance or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, or any violation by the Company of any rule or regulation promulgated by the Securities Act applicable to the Company and relating to any action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse each Holder and each Person controlling such Holder, for reasonable legal and other out-of-pocket expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred; provided that the Company will not be liable in any such case to the extent that any untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder for use in preparation of any Registration Statement, prospectus, amendment or supplement; provided further, that the Company will not be liable in any such case where the claim, loss, damage or liability arises out of or is related to the failure of such Holder to comply with the covenants and agreements contained in this Agreement respecting sales of Registrable Securities, and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary prospectus but eliminated or remedied in the amended prospectus on file with the Commission at the time any Registration Statement becomes effective or in an amended prospectus filed with the Commission pursuant to Rule 424(b) which meets the requirements of Section 10(a) of the Securities Act (each, a “Final Prospectus”), such indemnity shall not inure to the benefit of any such Holder or any such controlling Person, if a copy of a Final Prospectus furnished by the Company to the Holder for delivery was not furnished to the Person asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and a Final Prospectus would have cured the defect giving rise to such loss, liability, claim or damage.

6.5.2          Each Holder will severally, and not jointly, indemnify the Company, each of its directors and officers, and each Person who controls the Company within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 6.5.3 below), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any Registration Statement, prospectus, or any amendment or supplement thereof, incident to any such registration, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, and will reimburse the Company, such directors and officers, and each Person controlling the Company for reasonable legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred, in each case to the extent, but only to the extent, that such untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Holder expressly for use in preparation of any Registration Statement, prospectus, amendment or supplement; provided that the indemnity shall not apply to the extent that such claim, loss, damage or liability results from the fact that a current copy of a prospectus was not made available to the Person asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and a Final Prospectus would have cured the defect giving rise to such loss, claim, damage or liability. Notwithstanding the foregoing, a Holder’s aggregate liability pursuant to this Section 6.5.2 and Section 6.5.4 shall be limited to the net amount received by the Holder from the sale of the Registrable Securities.

6.5.3          Each party entitled to indemnification under this Section 6.5 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at its expense) to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such Indemnified Party’s expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement, unless such failure is materially prejudicial to the Indemnifying Party in defending such claim or litigation. An Indemnifying Party shall not be liable for any settlement of an action or claim effected without its written consent (which consent will not be unreasonably withheld). No Indemnifying Party, in its defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.

6.5.4          If the indemnification provided for in this Section 6.5 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 thereunder, 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 which resulted in such loss, liability, claim, damage or expense as well as 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 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.

6.6 Holder Obligations.

6.6.1          Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event requiring the preparation of a supplement or amendment to a prospectus relating to Registrable Securities so that, as thereafter delivered to the Holders, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, each Holder will forthwith discontinue disposition of Registrable Securities pursuant to a Registration Statement and prospectus contemplated by Section 6.1 until its receipt of copies of the supplemented or amended prospectus from the Company and, if so directed by the Company, each Holder shall deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

6.6.2          Each Holder shall suspend, upon request of the Company, any disposition of Registrable Securities pursuant to any Registration Statement and prospectus contemplated by Section 6.1 during no more than two periods of no more than 30 calendar days each during any 12-month period to the extent that the Board determines in good faith that the sale of Registrable Securities under any such Registration Statement would be reasonably likely to cause a violation of the Securities Act or Exchange Act.

6.6.3          As a condition to the inclusion of its Registrable Securities, each Holder shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing, including completing a Registration Statement Questionnaire in the form provided by the Company, or as shall be required in connection with any registration referred to in this Article 6.

6.6.4          Each Holder hereby covenants with the Company (a) not to make any sale of the Registrable Securities without effectively causing the prospectus delivery requirements under the Securities Act to be satisfied, and (b) if such Registrable Securities are to be sold by any method or in any transaction other than on a national securities exchange or in the over-the-counter market, in privately negotiated transactions, or in a combination of such methods, to notify the Company at least five (5) Business Days prior to the date on which the Holder first offers to sell any such Registrable Securities.

6.6.5          At the end of the Registration Period the Holders shall discontinue sales of shares pursuant to any Registration Statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by any such Registration Statement which remain unsold, and such Holders shall notify the Company of the number of shares registered which remain unsold immediately upon receipt of such notice from the Company.

6.7          Piggyback Registrations.

6.7.1          Right to Piggyback. For a period of five (5) years following the expiration of the Lock-Up Period, whenever the Company proposes to register the issuance or sale of any of its Common Stock under the Securities Act for its own account or otherwise, and the registration form to be used may be used for the registration of the resale of Registrable Securities (each, a “Piggyback Registration”) (except for the registrations on Form S-8 or Form S-4 or any successor form thereto) (a “Piggyback Registration Statement”), the Company will give written notice of the filing of such registration statement to the Holders and will use reasonable efforts to include in such registration all Registrable Securities that are no longer subject to the lock-up restrictions under Section 4.1 of this Agreement (in accordance with the priorities set forth in Sections 6.7.2 and 6.7.3 below) with respect to which the Company has received written requests for inclusion, which request shall specify the number of such Registrable Securities desired to be registered and be delivered within fifteen (15) days after the delivery of the Company’s notice. The Company may postpone or withdraw the filing or the effectiveness of a Piggyback Registration Statement at any time in its sole discretion.

6.7.2          Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary offering on behalf of the Company and the managing underwriters advise the Company in writing that in their opinion the number of Registrable Securities requested to be included in the registration creates a substantial risk that the price per share of the primary securities will be reduced or that the amount of the primary securities intended to be included on behalf of the Company will be reduced, then the managing underwriter and the Company may exclude securities (including Registrable Securities) from the registration and the underwriting, and the number of securities that may be included in such registration and underwriting shall include: (i) first, any securities that the Company proposes to sell, (ii) until the Existing Investors’ Rights Agreement Termination Date, (A) second, any securities proposed to be sold by the security holders then having registration rights under the Existing Investors’ Rights Agreement, and (B) third, on a pro rata basis based on the total number of Registrable Securities held by such Holders, any Registrable Securities proposed to be sold by the Holders, and (iii) thereafter, second, pari passu among the holders then having registration rights under the Existing Investors’ Rights Agreement and the Holders on a pro rata basis based on the total number of registrable securities held by such holders under the Existing Investors’ Rights Agreement and the total number of Registrable Securities held by the Holders.

6.7.3          Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary offering on behalf of holders of the Company’s securities and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in the registration creates a substantial risk that the price per share of securities offered thereby will be reduced, the Company will include in such registration: (i) until the Existing Investors’ Rights Agreement Termination Date (A) first any securities proposed to be sold by the security holders then having registration rights under the Existing Investors’ Rights Agreement and (B) second, on a pro rata basis based on the total number of Registrable Securities held by such Holders, any Registrable Securities proposed to be sold by the Holders, and (ii) thereafter, second, pari passu among the holders then having registration rights under the Existing Investors’ Rights Agreement and the Holders on a pro rata basis based on the total number of registrable securities held by such holders under the Existing Investors’ Rights Agreement and the total number of Registrable Securities held by the Holders.

6.7.4          Selection of Underwriters. In connection with any underwritten Piggyback Registration initiated by the Company, the Company shall have the right to (i) determine the plan of distribution and (ii) select the investment banker or bankers and managers to administer the offering, including the lead managing underwriter.

6.7.5          Payment of Expenses for Piggyback Registrations. All Registration Expenses incurred in connection with any registration, qualification, exemption or compliance pursuant to Section 6.7.1 shall be borne by the Company. All Selling Expenses relating to the sale of securities registered by or on behalf of each Holder pursuant to Section 6.7.1 shall be borne by such Holder on the basis of the number of securities so registered.

6.8 Commission Rule 144.

6.8.1 With a view to making available to the Holders the benefits of certain rules and regulations of the Commission which at any time permit the sale of the Registrable Securities to the public without registration, so long as the Holders still own Registrable Securities, the Company shall use its reasonable efforts to:

(a)

make and keep public information available, as those terms are understood and defined in Commission Rule 144, at all times;

(b)

file with the Commission in a timely manner all reports and other documents required of the Company under the Exchange Act; and

(c)

furnish to such Holder, upon any reasonable request, a written statement by the Company as to its compliance with Commission Rule 144, and of the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any such securities without registration.

6.9 Waiver. The rights of the Holders under any provision of this Article 6 may be waived (either generally or in a particular instance, either retroactively or prospectively and either for a specified period of time or indefinitely) or amended by an instrument in writing signed by Holders holding a majority of the Registrable Securities outstanding at such time.

This Agreement shall simultaneously and automatically terminate in the event that (a) the Collaboration Agreement terminates in its entirety for any reason, (b) the Purchase Agreement is terminated if such termination occurs before the Closing Date, or (c) 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.

7.6          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.

7.7          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.

7.8 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.

7.9 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.

7.10 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.

7.11 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.

7.13 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.

7.14 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.
