WHEREAS, pursuant to Section 7.2 of the License Agreement, as partial consideration for the grant by Purchaser to the Company of the licenses contemplated by the License Agreement, the Company desires to issue, and Purchaser desires to acquire, shares of Common Stock of the Company (the “Common Stock”) as herein described, on the terms and conditions hereinafter set forth.

NOW, THEREFORE, IT IS AGREED between the Parties as follows:

(b) Subject to the terms and conditions of this Agreement and provided the License Agreement is in full force and effect, upon the satisfaction of the Milestone Condition, the Company additionally agrees to issue to Purchaser, within the Milestone Issuance Time Period, the number of shares of Common Stock equal to the lesser of (i) an aggregate of 5,000,000 shares of Common Stock (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or similar recapitalization affecting such shares) and (ii) 200,000,000 divided by the Milestone Stock Price (the “Milestone Stock” and together with the Initial Stock, the “Stock”), at the Milestone Closing; provided, however, that if applicable, in no event shall fractional shares be issued in connection with the foregoing and the number of shares of Common Stock to be issued shall be rounded down to the nearest whole share (with the value of such fractional share paid to Purchaser in cash); provided further, that notwithstanding anything to the

contrary herein, if the closing of a Change of Control of the Company occurs prior to the issuance of the Milestone Stock at the Milestone Closing, then in lieu of issuing the Milestone Stock the Company agrees to pay to Purchaser after the satisfaction of the Milestone Condition and within the Milestone Issuance Time Period, a cash payment equal to the lesser of (1) $200,000,000 and (2) 5,000,000 (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or similar recapitalization affecting such shares) multiplied by the acquisition price per share paid for the Common Stock in the Change of Control of the Company (the “Milestone Condition Payment”), at the Milestone Closing.

(c) The initial closing hereunder, including delivery by the Company to Purchaser of a certificate representing the Initial Stock, shall occur on the Effective Date, or at such other time and place as the Parties may mutually agree (the “Initial Closing”). The relevant milestone closing hereunder, including the delivery by the Company to Purchaser of a certificate representing the Milestone Stock if applicable, shall occur at such time and place as the Parties may mutually agree (the “Milestone Closing”). The term “Closing” shall apply to the Initial Closing and the Milestone Closing unless otherwise specified.

(d) For clarity, the Milestone Closing shall occur only if the License Agreement is in full force and effect as of the date of such Milestone Closing and neither the Company nor Purchaser have terminated, or given written notice of its respective intent to so terminate, the HBV Program under the License Agreement. For further clarity, if the Milestone Closing has not occurred prior to the termination of the HBV Program or the Company’s or Purchaser’s written notice of its respective intent to terminate the HBV Program, then the Company’s obligation hereunder with respect to the Milestone Stock and the Milestone Condition Payment shall automatically terminate.

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

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

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

(iv) liability shall be limited to the Purchaser’s applicable share (determined based on the respective proceeds payable to each stockholder in connection with such Proposed Sale in accordance with the provisions of the Company’s Certificate of Incorporation) of a negotiated aggregate indemnification amount that applies equally to all holders of the Company’s Common Stock but that in no event exceeds the amount of consideration otherwise payable to the Purchaser in connection with such Proposed Sale, except with respect to claims related to fraud by the Purchaser, the liability for which need not be limited as to the Purchaser;

Execution Version

(v) upon the consummation of the Proposed Sale the Purchaser will receive the same amount of consideration per share of Common Stock as is received by other holders in respect of their shares of Common Stock; provided, however, that, notwithstanding the foregoing, if the consideration to be paid in exchange for shares of the Stock includes any securities and due receipt thereof by the Purchaser would require under applicable law (x) the registration or qualification of such securities or of any person as a broker or dealer or agent with respect to such securities; or (y) the provision to the Purchaser of any information other than such information as a prudent issuer would generally furnish in an offering made solely to “accredited investors” as defined in Regulation D promulgated under the Act, the Company may cause to be paid to the Purchaser in lieu thereof, against surrender of the shares of the Stock, which would have otherwise been sold by the Purchaser, an amount in cash equal to the fair value (as determined in good faith by the Company) of the securities which the Purchaser would otherwise receive as of the date of the issuance of such securities in exchange for the shares of the Stock; and

(vi) subject to Section 3(b)(v), requiring the same form of consideration to be available to the holders of any single class or series of capital stock, if any holders of any capital stock of the Company are given an option as to the form and amount of consideration to be received as a result of the Proposed Sale, all holders of such capital stock will be given the same option; provided, however, that nothing in this Subsection 3(b)(vi) shall entitle any holder to receive any form of consideration that such holder would be ineligible to receive as a result of such holder’s failure to satisfy any condition, requirement or limitation that is generally applicable to the Company’s stockholders.

(c) The Purchaser shall not be a party to any Stock Sale unless all holders of Preferred Stock are allowed to participate in such transaction and the consideration received pursuant to such transaction is allocated among the parties thereto in the manner specified in the Company’s Certificate of Incorporation in effect immediately prior to the Stock Sale (as if such transaction were a Deemed Liquidation Event).
